Search for supersymmetry in events with one lepton and multiple jets in proton-proton collisions at sqrt(s) = 13 TeV
Creators: name: CMS Collaboration

Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A search for supersymmetry is performed in events with a single electron or muon in proton-proton collisions at a center-of-mass energy of 13 TeV. The data were recorded by the CMS experiment at the LHC and correspond to an integrated luminosity of 2.3 inverse femtobarns. Several exclusive search regions are defined based on the number of jets and b-tagged jets, the scalar sum of the jet transverse momenta, and the scalar sum of the missing transverse momentum and the transverse momentum of the lepton. The observed event yields in data are consistent with the expected backgrounds from standard model processes. The results are interpreted using two simplified models of supersymmetric particle spectra, both of which describe gluino pair production. In the first model, each gluino decays via a three-body process to top quarks and a neutralino, which is associated with the observed missing transverse momentum in the event. Gluinos with masses up to 1.6 TeV are excluded for neutralino masses below 600 GeV. In the second model, each gluino decays via a three-body process to two light quarks and a chargino, which subsequently decays to a W boson and a neutralino. The mass of the chargino is taken to be midway between the gluino and neutralino masses. In this model, gluinos with masses below 1.4 TeV are excluded for neutralino masses below 700 GeV.

description: Integrative Conjugative Elements (ICEs) are mosaics containing functional modules allowing maintenance by site-specific integration and excision into and from the host genome and conjugative transfer to a specific host range. Many ICEs encode a range of adaptive functions that aid bacterial survival and evolution in a range of niches. ICEs from the SXT/R391 family are found in γ-Proteobacteria. Over 100 members have undergone epidemiological and molecular characterization allowing insight into their diversity and function. Comparative analysis of SXT/R391 elements from a wide geographic distribution has revealed conservation of key functions, and the accumulation and evolution of adaptive genes. This evolution is associated with gene acquisition in conserved hotspots and variable regions within the SXT/R391 ICEs catalysed via element-encoded recombinases. The elements can carry IS elements and transposons, and a mutagenic DNA polymerase, PolV, which are associated with their evolution. SXT/R391 ICEs isolated from different niches appear to have retained adaptive functions related to that specific niche; phage resistance determinants in ICEs carried by wastewater bacteria, antibiotic resistance determinants in clinical isolates and metal resistance determinants in bacteria recovered from polluted environments/ocean sediments. Many genes found in the element hotspots are undetermined and have few homologs in the nucleotide databases.

description: The banking sector in Ethiopia has experienced massive competition among themselves with the introduction of Multiple E-banking service specially after 2010 .In order to minimize their operational costs, and for some other reason commercial banks in Ethiopia have adopted Electronic banking including ATMs, mobile banking and internet banking, POS, PDA and the like where customer can access their accounts in different ways. It can make basic financial services more accessible by minimizing time and distance to the nearest retail bank branches as well as reducing the bank's own overheads and transaction- related costs and also enable them to have wider Coverage. The purpose of this study is to examine the effect of e-banking service quality dimensions on customer's satisfaction of Commercial Bank of Ethiopia. Explanatory Research Design with Quantitate Research approach were employed. Both Primary and secondary Data were used during this research work. Primary Data was collected via selfadministered 360 questionnaires from the population of customers of 20 branches (five branches from each four districts) of CBE in Addis Ababa by using non-probability sampling approach particularly convenient sampling technique. As secondary Sources Different related literature with the topic under study were used .The constructs in this study were developed by using measurement scales adopted from prior studies. The instrument was evaluated for reliability and validity. Data were analyzed using SPSS Version 20. Results of this study indicated that E-banking service quality was directly associated with customer perceived service quality. The results in this study indicate that Reliability; Responsiveness; Ease of use; Personalization; Security; and Website design have influence on customer's satisfaction of e-banking. In summary, findings provided evidence that E-banking service quality dimensions were influential on customer perceived service quality. Security Dimension and Ease of Use dimension has rated as the most and least Significant Service Quality Dimension respectively. The researcher concludes that there is a linear relationship between e-banking service quality and customer satisfaction. Management of bank needs to view and think from customers' perspectives so that the management understands customers' expectations.

The Pairing of Accreting Massive Black Holes in Multiphase Circumnuclear Disks: the Interplay between Radiative Cooling, Star Formation, and Feedback Processes

description: We study the orbital decay of a pair of massive black holes (BHs) with masses 5 * 10^5 and 10^7 M_sun, using hydrodynamical simulations of circumnuclear disks (CNDs) with the alternating presence of sub-grid physics such as radiative cooling, star formation, supernova feedback, BH accretion and feedback. In the absence of such processes, the orbit of the secondary BH decays over timescales of ~10 Myr to the center of the CND, where the primary BH resides. When strong dissipation operates in CNDs, fragmentation into massive objects the size of giant molecular clouds and with densities in the range 10^4 - 10^7 amu / cm^3 occurs, causing stochastic torques and hits that can eject the secondary BH from the midplane. Outside the plane, the low-density medium provides only weak drag, and the BH return is governed by inefficient dynamical friction. In rare cases, clump-BH interactions can lead to a faster decay. Feedback processes lead to outflows, but do not change significantly the overall density of the CND midplane. However, with a spherically distributed BH feedback a hot bubble is generated behind the secondary, which almost shuts off dynamical friction, a phenomenon we dub "wake evacuation", leading to delays in the decay of possibly ~0.3 Gyr. We discuss the non-trivial implications on the discovery space of the eLISA telescope. Our results suggest the largest uncertainty in predicting BH merger rates lies in the potentially wide variety of galaxy host systems, with different degrees of gas dissipation and heating, yielding decay timescales from ~10 to ~300 Myr.

Dynamical resonances of bars in PHANGS galaxies
Creators: name: Ruiz-García, Marina
Publisher: name: Zenodo
Year: 2023

description: Bars are remarkable stellar structures, which play an essential role in driving the secular evolution of galaxies, as they are expected to transport the gas towards the centre. In this study NIR images and ALMA CO(2-1) maps from the PHANGS survey are used to trace the stellar potential and the molecular gas distribution to determine the position of the main dynamical resonances of the bars in our targets. In this work, the gravitational torque method from García-Burillo et al. (2005) is used to locate the position of the corotation (CR), where stars and gas rotate at the same angular velocity as the bar. We have established the position of corotation for the 43 barred galaxies of the sample, which is composed of a total of 74 galaxies. Furthermore, a distinction has been made between fast and slow bars, by measuring R_CR/R_bar for every galaxy. We found that this variable has a mean value of 1.23 and standard deviation of 0.55, which is consistent with the value expected from theory R_CR/R_bar=1.2. Finally, we have also estimated other relevant resonances such as the Inner Lindblad Resonance (ILR) and the Outer Lindblad Resonance (OLR), where rings are expected to be formed. In this talk, we give an glimpse at our work, which provides a useful catalogue of resonances for nearby galaxies and emphasises the connection between bar dynamics and morphology, as the existence of fast and slow bars has cosmological implications for a scenario where bars may brake over time.

description: In this population synthesis work we study a variety of possible origin channels of supernovae type Ia (SNe Ia) Among them mergers of carbon-oxygen (CO) and oxygen-neon (ONe) white dwarfs (WDs) under the influence of gravitational waves are considered as the primary channel of SNe Ia formation. We estimated frequencies of mergers of WDs with different chemical compositions and distributions of masses of merging WDs. We computed the dependence of the ratio of merger frequencies of ONe and CO WDs as primaries in corresponding binaries on time. The scatter of masses of considered sources (up to the factor $1.5-2$) of SNe Ia is important and should be carefully studied with other sophisticated methods from theoretical point of view. Our ``game of parameters'' potentially explains the increased dimming of SNe Ia in the redshift range $z\approx 0.5-1$ by the changes in the ratio of ONe and CO WDs, i.e., to describe the observed accelerated expansion of the Universe in terms of the evolution of properties of SNe Ia instead of cosmological explanations. This example shows the extreme importance of theoretical studies of problems concerning SNe Ia, because evolutionary scenario and parameter games in nature potentially lead to confusions in their empirical standardization and, therefore, they can influence on cosmological conclusions.

description: The aim of this study is to investigate whether there exists a correlation between the bar length and the cosmic environment. To compare two distributions of barred spiral galaxies in two distinct environments,we use the galaxy sample
 selected from Galaxy Zoo 2 and identify within those galaxies inhabiting voids, by cross-matching it with the sample of the CalarAlto Void Integral-field Treasury surveY (CAVITY) project. The results obtained indicate that galaxies that reside in the less dense regions of the Universe have a higher probability of having shorter bars.

description: Imperata cylindrica (L.) P. Beauv. is an invasive species widely used in treatment of several diseases associated with pain and inflammation in different countries including Madagascar. This work aims to report the isolation of the antioxidant, analgesic and anti-nflammatory compounds from the methanol extract of I. cylindrica. The bio-guided method was used to isolate its bioactive compounds by combining chromatographic methods, writhing test in mice and antioxidant assays. Stigmast-4-en-3-one was isolated as one among the compounds responsible for the analgesic and anti-inflammatory properties and isovanillin as one among the antioxidant compounds from the extract. Stigmast-4-en-3-one showed a good oral pharmacokinetic profile and good binding affinities with some pro-inflammatory targets. It did not show any mutagenic effect, nor a carcinogenic one and had a low risk to be a cardiotoxic agent. All of our results provide scientific justification for its traditional medicinal use in the management of pain and inflammatory related diseases.
Assessment of Women Army Members' Empowerment at Strategic and Operational Leadership Positions; the Case of Ethiopian Ministry of National Defence.

description: Issues of women empowerment and participation in high leadership or decision making positions are becoming the centre stages in the discourse of global development. Enhancement of women participation and improve their empowerment with intent to the gender equality has to get due focus to enable them uplifted to the decision making role they can play. Role of women in defence strength and effectiveness in the same way is crucial and has to get special concern and commitment of the leadership, put ways of enforcement mechanism for the success. The problem pushed the researcher to make his study on women empowerment was that due to his work field, he had an opportunity to meet leaders at all levels of leadership and observed there was no woman at strategic and operational leadership positions; all the stated positions were seen occupied by men leaving all high ranked women at third lower level/ tactical/ leadership positions and struck him to make his study on the Assessment of Women army members' empowerment at strategic and Operational leadership positions. The objective of the study was to assess the current gap on women empowerment at strategic and operational leadership positions in national defence i.e. To justify leadership positions occupied by women as compared to men and To identify the challenges that hinder women to come up to the stated positions through the questions specified as, Do women in the national defence enjoy empowerment in strategic and operational leadership positions equal to the men? What areas of leadership positions do women occupy in the organization as compared to men? What challenges hinder women to come up to the stated leadership positions? That answered successfully. Method of the study was both quantitative and qualitative research approaches so as to meet the set objectives. The findings collected from the study showed that there are challenges such as absence of gender related guideline, lack of enforcement mechanism to the gender mainstreaming issues incorporated in organizational laws, Lesser effort on women capacity building, Lack of commitment and accountability on all the concerned leaders to identify the gap and put strategic direction to fill the gap. Therefore, The organization has to put implementation mechanism as mere presence of policy and strategic documents has no value, women have strengthen their organization to have power and show commitment to enforce the rights they have; male have to be endured to put their all round support

description: The accretion flow / jet correlation in neutron star (NS) low-mass X-ray binaries (LMXBs) is far less understood when compared to black hole (BH) LMXBs. In this paper we will present the results of a dense multi-wavelength observational campaign on the NS LMXB 4U 1820-30, including X-ray (Nicer, NuSTAR and AstroSAT) and quasi-simultaneous radio (ATCA) observations in 2022. 4U 1820-30 shows a peculiar 170 day super-orbital accretion modulation, during which the system evolves between "modes" of high and low X-ray flux. During our monitoring, the source did not show any transition to a full hard state. X-ray spectra were well described using a disc blackbody, a Comptonisation spectrum along with a Fe K emission line at 6.6 keV. Our results show that the observed X-ray flux modulation is almost entirely produced by changes in the size of the region providing seed photons for the Comptonisation spectrum. This region is large (about 15 km) in the high mode and likely coincides with the whole boundary layer, while it shrinks significantly (<10 km) in low mode. The electron temperature of the corona and the observed RMS variability in the hard X-rays also exhibit a slight increase in low mode. As the source moves from high to low mode, the radio emission due to the jet becomes about 5 fainter. These radio changes appear not to be strongly connected to the hard-to-soft transitions as in BH systems, while they seem to be connected mostly to variations observed in the boundary layer.

description: Light-matter interfaces enable the generation of entangled states of light and matter which can be exploited to steer the quantum state of matter through measurement of light and feedback. Here we consider continuous-time, interferometric homodyne measurements of light on an array of light-matter interfaces followed by local feedback acting on each material system individually. While the systems are physically non-interacting, the feedback master equation we derive describes driven-dissipative, interacting many-body quantum dynamics, and comprises pairwise Hamiltonian interactions and collective jump operators. We characterize the general class of driven-dissipative many body systems which can be engineered in this way, and derive necessary conditions on models supporting non-trivial quantum dynamics beyond what can be generated by local operations and classical communication. We provide specific examples of models which allow for the creation of stationary many-particle entanglement, and the emulation of dissipative Ising models. Since the interaction between the systems is mediated via feedback only, there is no intrinsic limit on the range or geometry of the interaction, making the scheme quite versatile.

description: Building on recent NMR experiments [Phys. Rev. Lett. 118, 067203], we theoretically investigate the high magnetic field regime of the disordered quasi-one-dimensional $S=1$ antiferromagnetic material Ni(Cl$_{1-x}$Br$_x$)$_2$-4SC(NH$_2$)$_2$. The interplay between disorder, chemically controlled by Br-doping, interactions, and the external magnetic field, leads to a very rich phase diagram. Beyond the well-known antiferromagnetically ordered regime, analog of a Bose condensate of magnons, which disappears when $H\ge 12.3$ T, we unveil a resurgence of phase coherence at higher field $H\sim 13.6$ T, induced by the doping. Interchain couplings stabilize finite temperature long-range order whose extension in the field - temperature space is governed by the concentration of impurities $x$. Such a "mini-condensation" contrasts with previously reported Bose-glass physics in the same regime, and should be accessible to experiments.

description: We present a comprehensive analysis of X-ray pulsar 4U 1626-67 during its current spin-down (2SD) state, following a recent torque reversal. Since its discovery, this ultra-compact binary has experienced multiple torque states, transitioning from spin-up (1SU) during 1977-1990 to spin-down (1SD) during 1990-2008, and again spin-up (2SU) until 2023. From NuSTAR observation of May 2023, we have investigated the timing and spectral properties of this pulsar during its 2SD phase, while also comparing them with previous spin-up-down states. For energies upto 8 keV, a distinct bi-horned pulse profile was observed during the spin-up phase, while several sub-structures emerged during spin-down. Beyond 8 keV, a broad asymmetric peak was consistently observed across all torque states. The pulse fraction during the 2SD phase was higher than that during 2SU phase. A prominent ~46.8 mHz quasi-periodic oscillation has been exclusively detected during the spin-down phase. The broadband spectrum during the 2SD phase is described by empirical NPEX model, cyclotron absorption feature and its first harmonic. The spectrum during 2SU phase requires an additional blackbody component and asymmetry in the cyclotron absorption line. A significant flux drop by a factor of ~3 in the 2SD was observed.

description: We introduce a novel gauge-invariant, quantized interband index in two-dimensional (2D) multiband systems. It provides a bulk topological classification of a submanifold of parameter space (e.g., an electron valley in a Brillouin zone), and therefore overcomes difficulties in characterizing topology of submanifolds. We confirm its topological nature by numerically demonstrating a one-to-one correspondence to the valley Chern number in $k\cdot p$ models (e.g., gapped Dirac fermion model), and the first Chern number in lattice models (e.g., Haldane model). Furthermore, we derive a band-resolved topological charge and demonstrate that it can be used to investigate the nature of edge states due to band inversion in valley systems like multilayer graphene.

description: In this report, the methodological framework that supports the integrated eco-design of electrical vehicle components is applied. Aspects that present a potential critical environmental performance are identified as hotspots. Eco-design strategies and specific actions are recognized towards the reduction of these potential environmental results. Strategies and actions are studied for each of the life cycle stages: Production (raw material extraction, manufacturing and assembly); Use (energy consumption, driving cycle); and End-of-life (final waste management). Compiling the results from a dedicated webinar including an analytic hierarchy process, a ranking of the more significant and suitable actions for the eco-design of electrical vehicle components is presented.

description: Competitiveness is a complex concept, long debated in the worldwide specialized literature. There are noticed many ways in which there is defined competitiveness of the company, but no definition is universally accepted. Being inseparable from the notion of competition, the concept expresses at general level, the ability of individuals, companies, economies, regions etc. in this study, This indicates that MSEs owners and managers, micro and small enterprise development offices, the government and other stakeholders have little awareness on marketing challenges and their influences on growth and sustainability of the MSEs in general and marketing competitiveness in particular. Generally, 172 samples were drowning from the MSEs using proportional random sampling technique, from which the required data were generated and analyzed employing the descriptive research design. The finding reveals that the gender of the entrepreneurs is dominated by and is in favor of male entrepreneurs when compared to that of their female counterparts. The majority of respondents lacks the relevant experiences and operates as sole proprietors. Furthermore, business plan is found out to be used only to meet the requirements of the financial institutions rather than expansion of the business which is tied by appropriate policy and regulation in support of MSEs competitiveness. The result also revealed that small enterprises are operated mainly by the owners of the business themselves and hence their contributions to employment and income generation for others is very limited and partnership and cooperative form of organization is increasing so as to share limited public resources. Financial and machinery leasing constraint is found out as a general challenge to entrepreneurs of the small enterprises. In addition, different constraints such as, access to finance, market opportunities, resource measures are examined in leather manufacturing business where each factors are found to affect MSEs competitiveness in this sector.

description: For a family of $n$-dimensional periodic delay differential equations which encompasses a broad set of models used in structured population dynamics, the existence of a positive periodic solution is obtained under very mild conditions. The proof uses the Schauder fixed point theorem and relies on the permanence of the system. A general criterion for the existence of a positive periodic solution for Nicholson's blowflies periodic systems (with both distributed and discrete time-varying delays) is derived as a simple application of our main result, generalizing the few existing results concerning multi-dimensional Nicholson models. In the case of a Nicholson system with discrete delays all multiples of the period, the global attractivity of the positive periodic solution is further analyzed, improving results in recent literature.

description: For entropy driven balanced processes we obtain final states with Poisson, Bernoulli, negative binomial and Pólya distributions. We apply this both for complex networks and particle production. For random networks we follow the evolution of the degree distribution, $P_n$, in a system where a node can activate $k$ fixed connections from $K$ possible partnerships among all nodes. The total number of connections, $N$, is also fixed. For particle physics problems $P_n$ is the probability of having $n$ particles (or other quanta) distributed among $k$ states (phase space cells) while altogether a fixed number of $N$ particles reside on $K$ states.

description: We present the discovery of the eclipsing double white dwarf (WD) binary WDJ 022558.21-692025.38 that has an orbital period of 47.19 min. Following identification with the Transiting Exoplanet Survey Satellite, we obtained time-series ground based spectroscopy and high-speed multi-band ULTRACAM photometry which indicate a primary DA WD of mass 0.40 +- 0.04 Msol and a 0.28 +- 0.02 Msol mass secondary WD, which is likely of type DA as well. The system becomes the third-closest eclipsing double WD binary discovered with a distance of approximately 400 pc and will be a detectable source for upcoming gravitational wave detectors in the mHz frequency range. Its orbital decay will be measurable photometrically within 10 yrs to a precision of better than 1%. The fate of the binary is to merge in approximately 41 Myr, likely forming a single, more massive WD.

Uniqueness of static photon surfaces: Perturbative approach

description: A photon surface $S$ is defined as a three-dimensional timelike hypersurface such that any null geodesic initially tangent to $S$ continues to be included in $S$, like $r=3M$ of the Schwarzschild spacetime. Using analytic solutions to static perturbations of a Schwarzschild spacetime, we examine whether a nonspherical spacetime can possess a distorted static photon surface. It is shown that if the region outside of $r=3M$ is vacuum, no distorted photon surface can be present. Therefore, we establish the perturbative uniqueness for an asymptotically flat vacuum spacetime with a static photon surface. It is also pointed out that if matter is present in the outside region, there is a possibility that a distorted photon surface could form.

description: Many stony coral-dwelling fishes exhibit adaptations to deal with hypoxia among the branches of their hosts; however, no information exists on the respiratory ecophysiology of obligate fish associates of non-coral organisms such as sea anemones and sponges. This study investigated metabolic and behavioral interactions between two-band anemonefish (Amphiprion bicinctus) and bulb-tentacle sea anemones (Entacmaea quadricolor) at night. We measured the net dark oxygen uptake (VO2, μmol O2h–1) of fish–anemone pairs when partners were separate from each other, together as a unit, and together as a unit but separated by a mesh screen that prevented physical contact. We also measured the effects of water current on sea anemone VO2 and quantified the nocturnal behaviors of fish in the absence and presence of host anemones in order to discern the impacts of anemone presence on fish behavior. Net VO2 of united pairs was significantly higher than that of both separated pairs and united pairs that were separated by a mesh screen. Anemone VO2 increased with flow rate from 0.5 to 2.0cms–1, after which VO2 remained constant up to a water flow rate of 8.0cms–1. Furthermore, the percentage time and bout frequency of flow-modulating behaviors by fish increased significantly when anemones were present. We conclude that physical contact between anemonefish and sea anemones elevates the VO2 of at least one of the partners at night, and anemonefish behavior at night appears to oxygenate sea anemone hosts and to augment the metabolism of both partners.
Four essays on linear and extreme dependences in credit derivatives and equity markets

description: The dissertation investigates the linear and extreme dependence structures in credit derivatives and equity markets and studies their possible implications for asset pricing and portfolio management. Subsequent to the introduction in Chapter one, the second chapter deals with extreme dependence between the CDS spreads of major European banks and shows that the propensity of a bank to experience extreme co-movements in its CDS premia together with the market is priced in the bank's default swap spread during the recent financial crisis. The third chapter studies linear dependence structures in the liquidity of CDS contracts and investigates the impact of commonality in CDS liquidity on the pricing of credit default swaps. The fourth chapter extends the scope of the dissertation and additionally studies the dependence structures in equity markets as well as cross-dependences between credit derivatives and equity markets. The chapter analyzes the linear and extreme dependence between stock prices, stock liquidity, and credit risk using a dynamic vine copula model and proposes a liquidity- and credit-adjusted Value-at-Risk that enables risk managers to reliably forecast the total risk exposure of a stock investment. Finally, Chapter five investigates whether the choice of extreme dependence estimator affects the assessment of tail risks and has a significant impact on the validity and economic significance of key results from recent studies in the financial economics literature.
