Fast Fashion Retailing. Customer and Retailer's Perceptions
Creators: name: Coutinho De Arruda, Maria Cecilia
name: Palmeira, Mirian
Publisher: name: International Journal of Economic Behavior
Year: 2016

description: The aim is to describe the customers and street retailers’ perceptions related to Fast Fashion. The results, through qualitative and quantitative research, from samples selected by convenience, of 20 Fast Fashion street retailers in Sao Paulo City, Brazil and 80 young people aged between 18 and 30 years old that live in Curitiba, Parana, show that one of the major differentials of Fast Fashion (F/F) in Brazil could be credit conditions. It seems that there is a tendency that customers with some F/F knowledge and level of F/F consumption present positive perception of F/F quality, design and price. Retail companies should focus on the timing of the collections. The issue is to show how important is the Business Schools’ role in a way to develop contents linked to Fashion and its different categories, such as Fast Fashion Retailing and to prepare the future professionals to deal with such different façades of Fashion.

description: In this work, we study the doubly charmed dibaryon states with the $qqqqcc$ ($q =u, d, s$) configuration. The mass spectra of doubly charmed dibaryon states are obtained systematically within the chromomagnetic interaction model. In addition to the mass spectrum analysis, we illustrate their two-body strong decay behaviours. Our results suggest that there may be narrow states or even stable states that cannot decay through the strong interaction. We hope that our results will provide valuable information for further experimental searches for doubly charmed dibaryon states.

Exploring the cannabis microbiome to develop safe and sustainable bio-fungicide
Creators: name: Dumigan, Christopher Robert
Publisher: name: University of British Columbia
Year: 2024

description: Cannabis plants are hosts to a variety of fungal pathogens that have limited tools for control. Studying the microbiome of other crops shows that microorganisms can play an integral role in plant health by antagonizing pathogens, promoting plant vigor, and creating a functioning community or a “healthy” microbiome. Furthermore, plant-associated microorganisms can be passed down plant generations to germinating seedlings by their mother plant and vectored by seed. These can be both pathogenic and beneficial to their host plant. This thesis investigates the microbiome of Cannabis plants and the activities that both beneficial and pathogenic microorganisms have on this crop. Investigating 15 genotypes of Cannabis grown to seed across western Canada showed both hemp and marijuana inherit a closely related group of bioactive and anti-fungal endophytic bacilli. 13 of these isolates were able to antagonize known fungal pathogens of Cannabis that were also seed-borne, suggesting co-evolution and potential symbiosis between Cannabis and this class of bacteria. Mature Cannabis plants are infected by a growing number of fungal diseases. Documented here is the first report of Berkeleyomyces rouxiae infecting drug-type Cannabis causing black root-rot. This fungal pathogen was isolated from an aeroponics facility in Cranbrook BC and was not identified due to a lack of genomic resources on this fungal species. Here the first whole genome sequence is provided using hybrid genome sequencing and assembly. Finally, this thesis investigates the relative contributions of both seed and soil bacteria in shaping the endosphere communities in germinating Cannabis seedlings. A multifactorial metagenomic experiment was performed using three genotypes of Cannabis with two soil types, both of which were treated and untreated with autoclave sterilization. Cannabis genotype, soil type, and soil sterilization all play a role in structuring the endophyte communities of germinating Cannabis seedlings. This suggests inoculum from both seed and soil shape the microbiome of germinating Cannabis seedlings. There was however a shared element of the microbiome conserved across genotypes, soil types, and soil sterilization, indicating seed-borne endophytes are maintained across these conditions. Soil, however, had a dramatic and significant role in shaping the diversity and abundance of bacteria in this niche.

description: We show that the carrier-mediated exchange interaction, the so-called RKKY coupling, between two magnetic impurity moments in graphene is significantly modified in the presence of electron-electron interactions. Using the mean-field approximation of the Hubbard-$U$ model we show that the $(1+\cos(2{\bf k}_D\cdot {\bf R})$-oscillations present in the bulk for non-interacting electrons disappear and the power-law decay becomes more long ranged with increasing electron interactions. In zigzag graphene nanoribbons the effects are even larger with any finite $U$ rendering the long-distance RKKY coupling distance independent. Comparing our mean-field results with first-principles results we also extract a surprisingly large value of $U$ indicating that graphene is very close to an antiferromagnetic instability.

Publisher: name: International Journal of Economic Behavior
Year: 2017

description: Expanding from Veblen’s conspicuous consumption theory, this paper provides new explanations on China’s household saving behavior. Using provincial level data, it finds evidence that urbanization, increased mobility of the population, and a greater degree of openness all depress household saving, likely through higher conspicuous consumption. This result is robust with different estimators and specifications. Among the conventional explanatory variables, the paper finds support for the permanent income theory, but little evidence for the life cycle theory..

description: We consider the most general solutions of eleven-dimensional supergravity preserving $N=2$ supersymmetry whose metrics are warped products of three-dimensional anti-de Sitter space with an eight-dimensional manifold, focusing on those realising (2,0) superconformal symmetry. We give a set of necessary and sufficient conditions for a solution to be supersymmetric, which can be phrased, in the general case, in terms of a local SU(2) structure and its intrinsic torsion. We show that these supergravity backgrounds always admit a nowhere-vanishing Killing vector field that preserves the solution and encodes the U(1) R-symmetry of the dual field theory. We illustrate our results with examples which have appeared in the literature, including those with SU(4), G$_2$ and SU(3) structures, and discuss new classes of Minkowski solutions.

description: One of the biggest concerns among cybersecurity professionals these days is the hype around quantum computing, its incomprehensible power, and its implications. The advancement in quantum computing has the potential to revolutionize our daily lives, but it can also completely break down the Internet as we know it. Mathematicians and physicists have developed algorithms based on quantum computing, which can change the Internet security paradigm. This article discusses quantum computing key concepts, with a special focus on quantum Internet, quantum key distribution, and related challenges.
Spectral variability of ultraluminous X-ray sources

description: We study spectral variability of 11 ultraluminous X-ray sources (ULX) using archived XMM-Newton and Chandra observations. We use three models to describe the observed spectra: a power-law, a multi-colour disc (MCD) and a combination of these two models. We find that 7 ULXs show a correlation between the luminosity Lx and the photon index Gamma. Furthermore, 4 out of these 7 ULXs also show spectral pivoting in the observed energy band. We also find that two ULXs show an Lx-Gamma anti-correlation. The spectra of 4 ULXs in the sample can be adequately fitted with a MCD model. We compare these sources to known black hole binaries (BHB) and find that they follow similar paths in their luminosity-temperature diagrams. Finally we show that the `soft excess' reported for many of these ULXs at about 0.2 keV seems to roughly follow a trend Lsoft \propto T^{-3.5} when modelled with a power-law plus a `cool' MCD model. This is contrary to the L \propto T^4 relation that is expected from theory and what is seen for many accreting BHBs. The observed trend could instead arise from disc emission beamed by an outflowing wind around a about 10 solar mass black hole.

description: We show combinatorially that the higher-order matching polynomials of several families of graphs are d-orthogonal polynomials. The matching polynomial of a graph is a generating function for coverings of a graph by disjoint edges; the higher-order matching polynomial corresponds to coverings by paths. Several families of classical orthogonal polynomials -- the Chebyshev, Hermite, and Laguerre polynomials -- can be interpreted as matching polynomials of paths, cycles, complete graphs, and complete bipartite graphs. The notion of d-orthogonality is a generalization of the usual idea of orthogonality for polynomials and we use sign-reversing involutions to show that the higher-order Chebyshev (first and second kinds), Hermite, and Laguerre polynomials are d-orthogonal. We also investigate the moments and find generating functions of those polynomials.

description: The rapid growth of remote healthcare delivery has introduced significant security and privacy risks to protected health information (PHI). Analysis of a comprehensive healthcare security breach dataset covering 2009-2023 reveals their significant prevalence and impact. This study investigates the root causes of such security incidents and introduces the Attacker-Centric Approach (ACA), a novel threat model tailored to protect PHI. ACA addresses limitations in existing threat models and regulatory frameworks by adopting a holistic attacker-focused perspective, examining threats from the viewpoint of cyber adversaries, their motivations, tactics, and potential attack vectors. Leveraging established risk management frameworks, ACA provides a multi-layered approach to threat identification, risk assessment, and proactive mitigation strategies. A comprehensive threat library classifies physical, third-party, external, and internal threats. ACA's iterative nature and feedback mechanisms enable continuous adaptation to emerging threats, ensuring sustained effectiveness. ACA allows healthcare providers to proactively identify and mitigate vulnerabilities, fostering trust and supporting the secure adoption of virtual care technologies.

Year: 2017

description: The processes for exploitation of knowledge became an essential element for firms to adapt to changes in the competitive environment. The exploitation of this knowledge should be undertaken with proactivity, innovation and risk-taking. Building on well established theories, our research explores the influence of entrepreneurial orientation in exploitation of knowledge of Portuguese small and medium enterprises (SMEs) of footwear associated to the Portuguese Footwear, Components and Leather Goods Association (APICCAPS). Based on survey data from 42 firms, and employing the Partial Least Squares Structural Equation Modeling (PLS-SEM) technique, our empirical results indicate that the entrepreneurial orientation’s dimensions that have a positive and significant influence on knowledge’s exploitation are innovation and risk-taking, and that on the contrary proactiveness has a negative and a not significant influence on it.

description: Aiming at selecting a small subset of nodes with maximum influence on networks, the Influence Maximization (IM) problem has been extensively studied. Since it is #P-hard to compute the influence spread given a seed set, the state-of-the-art methods, including heuristic and approximation algorithms, faced with great difficulties such as theoretical guarantee, time efficiency, generalization, etc. This makes it unable to adapt to large-scale networks and more complex applications. On the other side, with the latest achievements of Deep Reinforcement Learning (DRL) in artificial intelligence and other fields, lots of works have been focused on exploiting DRL to solve combinatorial optimization problems. Inspired by this, we propose a novel end-to-end DRL framework, ToupleGDD, to address the IM problem in this paper, which incorporates three coupled graph neural networks for network embedding and double deep Q-networks for parameters learning. Previous efforts to solve IM problem with DRL trained their models on subgraphs of the whole network, and then tested on the whole graph, which makes the performance of their models unstable among different networks. However, our model is trained on several small randomly generated graphs with a small budget, and tested on completely different networks under various large budgets, which can obtain results very close to IMM and better results than OPIM-C on several datasets, and shows strong generalization ability. Finally, we conduct a large number of experiments on synthetic and realistic datasets, and experimental results prove the effectiveness and superiority of our model.

description: The main objective of this paper is to consider the role of Made in Italy in foreign markets, especially in the German one. The focus is on the Italian Sounding phenomenon, which is mainly affecting the Italian food sector. To deeply understand this phenomenon and its consequences, an online survey has been carried out in Germany. By analyzing results, the fact that consumers do not pay attention to the label while purchasing has been confirmed. In this way, the strategy of Italian Sounding damages both the perception of Made in Italy goods and the whole Italian economy. For those reasons, the Italian Sounding should be minimized by using specific marketing activities, until consumers understand the real quality of the authentic Made in Italy..

description: A universal characterization of interactions in few- and many-body quantum systems is often possible without detailed description of the interaction potential, and has become a defacto assumption for cold atom research. Universality in this context is defined as the validity to fully characterize the system in terms of two-body scattering length. We discuss universality in the following three contexts: closed-channel dominated Feshbach resonance, Efimov physics near Feshbach resonances, and corrections to the mean field energy of Bose-Einstein condensates with large scattering lengths. Novel experimental tools and strategies are discussed to study universality in ultracold atomic gases: dynamic control of interactions, run-away evaporative cooling in optical traps, and preparation of few-body systems in optical lattices.

description: Insider threats (InTs) within organizations are small in number but have a disproportionate ability to damage systems, information, and infrastructure. Existing InT research studies the problem from psychological, technical, and educational perspectives. Proposed theories include research on psychological indicators, machine learning, user behavioral log analysis, and educational methods to teach employees recognition and mitigation techniques. Because InTs are a human problem, training methods that address InT detection from a behavioral perspective are critical. While numerous technological and psychological theories exist on detection, prevention, and mitigation, few training methods prioritize psychological indicators. This literature review studied peer-reviewed, InT research organized by subtopic and extracted critical theories from psychological, technical, and educational disciplines. In doing so, this is the first study to comprehensively organize research across all three approaches in a manner which properly informs the development of an InT education platform.

Rate and Detection-Error Exponent Tradeoff for Joint Communication and Sensing of Fixed Channel States

description: We study the information-theoretic limits of joint communication and sensing when the sensing task is modeled as the estimation of a discrete channel state fixed during the transmission of an entire codeword. This setting captures scenarios in which the time scale over which sensing happens is significantly slower than the time scale over which symbol transmission occurs. The tradeoff between communication and sensing then takes the form of a tradeoff region between the rate of reliable communication and the state detection-error exponent. We investigate such tradeoffs for both mono-static and bi-static scenarios, in which the sensing task is performed at the transmitter or receiver, respectively. In the mono-static case, we develop an exact characterization of the tradeoff in open-loop, when the sensing is not used to assist the communication. We also show the strict improvement brought by a closed-loop operation, in which the sensing informs the communication. In the bi-static case, we develop an achievable tradeoff region that highlights the fundamentally different nature of the bi-static scenario. Specifically, the rate of communication plays a key role in the characterization of the tradeoff and we show how joint strategies, which simultaneously estimate message and state, outperform successive strategies, which only estimate the state after decoding the transmitted message.

Enhancing sewer asset management using machine learning algorithms

Publisher: name: University of British Columbia

description: Closed-circuit television (CCTV) is widely employed for assessing defects in sewers. This thesis: i) develops a number of deep convolutional neural network (CNN)-based image classification models for identifying sewer defects in CCTV videos, ii) develops a number of Machine Learning (ML)-based models for predicting the likely occurrence of specific defects in sewer networks, as well as identifying the factors that contribute to these defects, and iii) analyses the model performances with data from multiple utilities. The image classification models are trained and tested using images extracted from CCTV inspection videos for three utilities. They are analysed for serving two purposes: conducting a quality assurance and quality control (QA/QC) assessment of manual inspection reports of previously inspected videos, and identifying defects in images from videos that have not yet been manually inspected. Models are developed based on three pre-trained CNN backbone architectures: MobileNet V3 Large, ResNet50, and ResNet101; two model configurations: one- and two-stage models; and grouped classes. Two-stage models result in higher performance compared with alternative approaches. For QA/QC, on average, the ResNet models outperform MobileNet V3 Large where model accuracies for Utilities A, B, and C, are 0.95, 0.70, and 0.98, respectively. For recognizing defects in videos not previously viewed, the optimal model for each of the three utilities does not perform well. However, all models possess the ability to distinguish between non-defective and defective images with accuracies higher than 0.50, where the Utility A model achieves an accuracy of 0.80. Multiple decision tree-based ML models that predict the likely occurrence of infiltration and structural defects are developed using data from CCTV inspections coupled with additional pipe information and Geographical Information System files for two utilities. The performance of the models is assessed using the area under the Receiver Operating Characteristics (AUC-ROC) and Precision Recall (AUC-PR) curves. LightGBM-based models with cost-sensitive learning show the best performance overall when predicting infiltration and structural defects. The best performing model achieves an AUC-ROC of 0.79 and an AUC-PR of 0.62. For these utilities, an application of SHapley Additive exPlanations (SHAP) shows that the most important factors are “pipe location” and “pipe age”.

description: Time resolved photoluminescence is a powerful technique to study the collective dynamics of excitons and polaritons in semiconductor nanostructures. We present a two excitation pulses technique to induce the ultrafast and controlled quenching of the exciton emission in a quantum well. The depth of the dip is given by the magnitude of the warming of the carriers induced by the arrival of a laser pulse when an exciton population is already present in the sample. We use this technique to study the relaxation mechanisms of polaritons in semiconductor microcavities, which are of great importance to enhance the conditions for their condensation under non-resonant excitation. We also explore the dynamics of polariton fluids resonantly created in the lower polariton branch in a triggered optical parametric oscillator configuration, showing evidence of polariton superfluidity, and opening up the way to the real-time study of quantum fluids.

description: To investigate whether semantic memory impairments in MTL amnesia can be understood with reference to a deficit in scene construction, the current study examined knowledge of scripts that vary in the extent to which they play out in a scene context in nine patients with MTL amnesia and eighteen healthy control subjects. Scripts are routine activities characterized by an ordered set of actions, including some that are essential for completing the activity. Comparing performance on scene-based scripts (e.g., buying groceries at the grocery store) and object-based scripts (e.g., addressing a letter), we found that patients generated the same number of total action steps as controls for both types of script, but patients were selectively impaired at generating essential actions steps for scene-based scripts. Furthermore, patients made more sequencing and idiosyncratic errors than controls in the scene-based, but not in the object-based, scripts. These findings demonstrate that the hippocampus plays a critical role in the retrieval of semantic knowledge about everyday activities when such retrieval entails scene construction.
PREJUDICE AND DISCRIMINATION IN SEASIDE RETAILING. COMPARATIVE ANALYSES BETWEEN BRAZIL AND ITALY
Creators: name: Palmeira, Mirian
Publisher: name: International Journal of Economic Behavior
Year: 2017

description: This paper focuses on the phenomena of prejudice and discrimination among the interactions of frontline employees and customers in retailing spatial environments. The aim is to identify if there is perception of prejudice and discrimination related to Ageism, Sexism, Lookism (ASL) and Sexual Orientation bias (SO) against customers in Brazil and Italy Seaside Retailing. Through quantitative research and descriptive study, data from Curitiba-Parana-Brazil and Urbino-Marche-Italy are collected, using sampling by convenience. Likert Scales have been used to evaluate ASL+SO. Findings: One statement (4.2 “The frontline male employees are nicer to younger female customers”), out of 15 shows that the interviewees from both countries had presented a highly agreement perception, which is the reinforcement that they had perceived that gender, age and appearance have influence on frontline employees’ behaviour. However, considering the results of the majority of the statements, an overall conclusion can highlight that the respondents do not perceive ageism, sexism, lookism or sexual orientation bias against customers when the seaside retail companies provide face-to-face services. A theoretical contribution of this paper can be drawn for the development of protocols that can be useful to identify and to evaluate ASL+SO phenomena in retailing. Its format and its methodology can be used to research different kinds of organisations, especially in the retail and services industries. The managerial implications are in the importance of developing T&D to reduce ASL+SO practices against customers and to include these issues as subjects in the organisation’s strategic statements. Also it would be suitable designing more efficient procedures of queueing management. These practices could avoid that dissatisfied customers reduce purchasing and consequent falling sales and profits.

We further provide four accompanying baselines for benchmarking potential future research. Additionally, we propose a new way of measuring the success of said extraction process by incorporating a word-level weighting scheme into the conventional F1 score to better model the inherently fuzzy borders of the entity pairs of a relation in this domain.

description: We test the modified Newtonian dynamics (MOND) theory with the velocity-dispersion profiles of Galactic globular clusters populating the outermost region of the Milky Way halo, where the Galactic acceleration is lower than the characteristic MOND acceleration a_0. For this purpose, we constructed self-consistent, spherical models of stellar systems in MOND, which are the analogues of the Newtonian King models. The models are spatially limited, reproduce well the surface-brightness profiles of globular clusters, and have velocity-dispersion profiles that differ remarkably in shape from the corresponding Newtonian models. We present dynamical models of six globular clusters, which can be used to efficiently test MOND with the available observing facilities. A comparison with recent spectroscopic data obtained for NGC2419 suggests that the kinematics of this cluster might be hard to explain in MOND.

However, the effect of quantum gravity could bring an energy dependence of light speed, and a series of studies on high-energy photon events from gamma-ray bursts (GRBs) and active galactic nuclei (AGNs) suggest a light speed variation $v(E)=c\left(1-E / E_{\mathrm{LV}}\right)$ with $E_{\mathrm{LV}}=3.6 \times 10^{17} ~\mathrm{GeV}$ or a bound $E_{\mathrm{LV}} \ge 3.6 \times 10^{17} ~\mathrm{GeV}$. From the newly observed gamma-ray burst GRB 221009A, we find that a 99.3~GeV photon detected by Fermi-LAT is coincident with the sharp spike in the light curves detected by both Fermi-GBM and HEBS under the above scenario of light speed variation, suggesting an option that this high-energy photon was emitted at the same time as a sharp spike of low-energy photon emission at the GRB source. Thus this highest energy photon event detected by Fermi-LAT during the prompt emission of gamma-ray bursts might be considered as an optional signal for the linear form modification of light speed in cosmological space.

Spitzer IRAC Detection and Analysis of Shocked Molecular Hydrogen Emission

description: We use statistical equilibrium equations to investigate the IRAC color space of shocked molecular hydrogen. The location of shocked H_2 in [3.6]-[4.5] vs [4.5]-[5.8] color is determined by the gas temperature and density of neutral atomic hydrogen. We find that high excitation H_2 emission falls in a unique location in the color-color diagram and can unambiguously be distinguished from stellar sources. In addition to searching for outflows, we show that the IRAC data can be used to map the thermal structure of the shocked gas. We analyze archival Spitzer data of Herbig-Haro object HH 54 and create a temperature map, which is consistent with spectroscopically determined temperatures.

description: Gravitational waves (GWs) emitted by binary sources are interesting signals for testing gravity on cosmological scales since they allow measurements of the luminosity distance. When followed by electromagnetic counterparts, in particular, they enable a reconstruction of the GW-distance-redshift relation. In the context of several modified gravity (MG) theories, even when requiring that the speed of propagation is equal to that of light, this GW distance differs from the standard electromagnetic luminosity distance due to the presence of a modified friction in the GW propagation. The very same source of this friction, which is the running of an effective Planck mass, also affects the scalar sector generating gravitational slip, i.e. a difference between the scalar potentials, an observable that can be inferred from large-scale structure (LSS) probes. In this work, we use a model within effective field theories for dark energy to exemplify precisely the fact that, at the linear perturbation level, parametrizing a single function is already enough to generate simultaneous deviations in the GW distance and the slip. By simulating multi-messenger GW events that might be detected by the Einstein Telescope in the future, we compare the constraining power of the two observables on this single degree of freedom. We then combine forecasts of a Euclid-like survey with GW simulations, coming to the conclusion that, when using Planck data to better constrain the cosmological parameters, those future data on the scalar and tensor sectors are competitive to probe such deviations from General Relativity, with LSS giving stronger (but more model-dependent) results than GWs.

A MULTICULTURAL STUDY ON THE IMPACT OF CULTURE ON THE QUALITY OF THE RELATIONSHIP BETWEEN EXPORTERS AND LOCAL DISTRIBUTORS.
Creators: name: Alves, Gisela
Publisher: name: International Journal of Economic Behavior
Year: 2017

description: This research is aimed at understanding the role of culture in the quality of the relationship between Portuguese exporting companies and their distributors in Angola. This study is particularly important because it is based on an analysis of exporting distributor pairs (matched pairs) i.e. Portuguese export companies and their distributors in Angola. This study aims to understand how culture has an impact on the quality of trade relationships established between companies in the internationalization of the business context. Also, note that in international contexts, the impact of the similarities/cultural differences on the relationship structures have not been particularly studied. In terms of methodology, we have chosen a qualitative analysis: five case studies of Portuguese exporting companies and five case studies of Angolan distributors were examined. Interviews with Directors/CEO of Portuguese exporting companies and boards responsible for export activities were carried out and the corresponding Angolan distributors in order to answer the research questions. The selection of the Portuguese companies was based on a list of the fifty largest exporters to Angola, provided by the Agency for Investment and Foreign Trade of Portugal, EPE (AICEP) in August 2011. In general, the results show that culture has an impact on the quality of the business relationships between the Portuguese exporting companies and the Angolan distributors Classification-JEL: Keywords: international marketing, culture, cross-cultural marketing, Exporters, distributors

Nonlinear coherent states and Ehrenfest time for Schrodinger equation

description: We consider the propagation of wave packets for the nonlinear Schrodinger equation, in the semi-classical limit. We establish the existence of a critical size for the initial data, in terms of the Planck constant: if the initial data are too small, the nonlinearity is negligible up to the Ehrenfest time. If the initial data have the critical size, then at leading order the wave function propagates like a coherent state whose envelope is given by a nonlinear equation, up to a time of the same order as the Ehrenfest time. We also prove a nonlinear superposition principle for these nonlinear wave packets.

Amplitude's positivity vs. subluminality: Causality and Unitarity Constraints on dimension 6 & 8 Gluonic operators in the SMEFT

description: We derive the causality and unitarity constraints on dimension 6 and dimension 8 Gluon field strength operators in the Standard Model Effective Field Theory (SMEFT). In the first part of the paper, we use the 'amplitude analysis' i.e. dispersion relation for $2\rightarrow2$ scattering in the forward limit, to put bounds on the Wilson coefficients. We show that the dimension 6 operators can exist only in the presence of certain dimension 8 operators. It is interesting that the square of the dimension 6 Wilson coefficients can be constrained in this case even at the tree level. In the second part of this work, we successfully rederive all these bounds using the classical causality argument that demands that the speed of fluctuations about any non-trivial background should not exceed the speed of light. We also point out some subtleties in the superluminality analysis regarding whether the low-frequency phase velocity can always be used as the relevant quantity for Causality violation: as an example, we show that, due to these subtleties, if a small pion mass is added in the chiral Lagrangian, it is unclear if any strict positivity bound can be derived on the dimension 8 Wilson coefficient. Finally, we mention an interesting non-relativistic example where the subluminality requirement produces a stronger bound than the 'amplitude analysis'.

Search for Higgs boson decays into a pair of pseudoscalar particles in the $γγτ_{\text{had}}τ_{\text{had}}$ final state using $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector

description: A search for exotic decays of the 125 GeV Higgs boson into a pair of new spin-0 particles, $H \to aa$, where one decays into a photon pair and the other into a $τ$-lepton pair, is presented. Hadronic decays of the $τ$-leptons are considered and reconstructed using a dedicated tagger for collimated $τ$-lepton pairs. The search uses 140 fb$^{-1}$ of proton-proton collision data at a centre-of-mass energy of $\sqrt{s}=13$ TeV recorded between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider. The search is performed in the mass range of the $a$ boson between 10 GeV and 60 GeV. No significant excess of events is observed above the Standard Model background expectation. Model-independent upper limits at 95$\% $ confidence level are set on the branching ratio of the Higgs boson to the $γγττ$ final state, $\mathcal{B}(H\to aa\to γγττ)$, ranging from 0.2$\% $ to 2$\% $, depending on the $a$-boson mass hypothesis.
