description: We study single production of exotic vectorlike $Y$ quark with electric charge $|Q_{Y}|=4/3$ and its subsequent decay at the High Luminosity LHC (HL-LHC). Most of the vector like quark (VLQ) decays have the electroweak $W$ bosons in the intermediate state. Besides their direct productions singly or pairs, the $W$-bosons are involved in decay chains as a result of the decay of a top quark which contributes to the background. This is particularly the case since vectorlike $Y$ quark, which is estimated to be produced with a high cross-section, can only decay via a $W$ boson and a down type quark ($d,s,b$). We calculate the cross sections of signal (for different couplings and mass values) and relevant Standard Model (SM) backgrounds. After a fast simulation of signal and background events, estimations of the sensitivity to the parameters (mass range 1000-2500 GeV for coupling value $κ_{Y}=0.5$, and mass range 500-2000 GeV for coupling values $κ_{Y}=0.3$ and $κ_{Y}=0.15$) have been presented at the HL-LHC with center of mass energy $\sqrt{s}=14$ TeV and integrated luminosity projections of 300 fb$^{-1}$, 1000 fb$^{-1}$ and 3000 fb$^{-1}$.

We relate our results to chiral perturbation theory in both, the epsilon-regime and in the p-regime. In particular we measured the pion decay constant by different methods, as well as the chiral condensate, light meson masses, the PCAC quark mass and the renormalisation constant Z_A.

description: We present a theoretical framework that accounts for the new $D_J$ and $D_{sJ}$ mesons measured in the open-charm sector. These resonances are properly described if considered as a mixture of conventional $P-$wave quark-antiquark states and four-quark components. The narrowest states are basically $P-$wave quark-antiquark mesons, while the dominantly four-quark states are shifted above the corresponding two-meson threshold, being broad resonances. We study the electromagnetic decay widths as basic tools to scrutiny their nature. The proposed explanation incorporates in a natural way the most recently discovered mesons in charmonium spectroscopy.

description: Since 1992, the European Union has protected high-quality agricultural products based on geographical origin using designations of geographical indications (GIs). U.S. producers and processors can obtain a type of trademark called a certification mark, which provides similar protections to that of GIs but protects products only within the United States. In the current round of the World Trade Organization (WTO) negotiations, the European Union and other countries are seeking to expand protection through GIs. If they achieve the full range of protection they are seeking, many U.S. producers and processors could no longer use many product names currently treated as generic (e.g., feta cheese). This article describes and contrasts three systems of protecting property rights for agricultural products (certification mark, E.U.-wide GI, and WTO GI) and discusses some of the benefits and problems of each system and the effects of each system on helping to differentiate and protect high-value U.S. agricultural products.

description: A spontaneous vortex state (SVS) between 30 K and 56 K was observed for the weak-ferromagnetic superconductor RuSr2GdCu2O8 with ferromagnetic Curie temperature TC = 131 K and superconducting transition temperature Tc = 56 K. The low field (20 G) Superconducting hysteresis loop indicates a narrow Meissner state region within average lower critical field Bc1(T)= Bc1(0)[1 - (T/T0)2], with average Bave c1 (0) = 12 G and T0 = 30 K. Full Meissner shielding signal in very low applied field indicates an ab-plane Bab c1(0) ~ 4 G with an estimated anisotropic parameter g ~ 7 for this layered system. The existence of a spontaneous vortex state between 30 K and 56 K is the result of weak-ferromagnetic order with a net spontaneous magnetic moment of ~ 0.1 muB/Ru, which generates a weak magnetic dipole field around 10 G in the CuO2 bi-layers. The upper critical field Bc2 varies linearly as (1 - T/Tc) up to 7-T field. The vortex melting line Bm varies as (1 - T/Tm)3.5 with melting transition temperature Tm = 39 K and a very broad vortex liquid region due to the coexistence and the interplay between superconductivity and weak-ferromagnetic order.

description: Children have always been part of the economic life of societies. Historical evidence indicates that the contribution of children to family income in cash or in kind has been consistently significant. Currently, the issue of child labor has become an important global development issue in academic research. Empirical evidence indicates that child laborers are found mostly in developing countries and are employed mainly in agriculture and related activities. The aim of this study was to examine the decision-making behavior of subsistence rural households with respect to allocating their children's unit-time endowment among competing activities, including work and school attendance. A multinomial logit model has been used to identify the social, economic and cultural factors influencing household's decision about the allocation of children's time using data from a survey of rural households in Ethiopia. The results show that there are a number of child- and household-specific attributes, culture-and location-specific factors as well as economic factors related to household wealth and technological development that affect the decision-making process. Improving the educational infrastructure, encouraging technological adoption and creating a more stable economic base for rural households could significantly contribute towards reducing the problem of child labor.

description: Small and medium enterprises are an important factor in the East African economies especially with respect to employment. The increasing competition through globalisation puts them under considerable pressure. Through the rapid spread of information and communication technologies (ICT) and ever decreasing prices for communication, markets in different parts of the world become more integrated. Therefore, one basic question is whether the use of ICT (as production technology, as information processing technology or as information communication technology) can help them to cope with these new challenges. Information asymmetries are one of the major causes for high transaction costs, uncertainty and therefore market failure. A reduction of the information gap also reduces the ability of the better informed to extract rents from the less informed be it buyers or sellers of goods or factors. A reduction of information asymmetry will also create new opportunities and therefore enhance the efficiency of resource allocation. On a macro level this will then lead to faster growth and diversification of the economy. Our sample of 300 SMEs in East Africa shows that the use of ICT by SMEs in Kenya as well as in Tanzania is increasing over time. The usage of fixed phone lines nearly reaches the saturation point but is still lower in Tanzania than in Kenya. The percentage of firms that uses mobile phones is increasing fast in both countries. Especially in Tanzania, despite its late start only in 1994 it has already outgrown the usage of fax machines. Those enterprises that use different forms of ICT rate their effects mostly positive. On top are computer applications that are assumed by 88 % and 76 % of users to considerably increase management efficiency and competitiveness respectively. Mobile phones are considered to contribute significantly to regional market expansion by most enterprises, followed by fixed phones and faxes. For all sectors in both countries the average size of enterprises is generally bigger for users of more advanced ICTs. The average years of schooling also increase with the use of advanced ICTs with only small differences between sectors. Also with respect to exporting the relation with ICT is positive and similar for all sectors. By regressing a Cobb-Douglas production function on a dataset of Kenyan and Tanzanian enterprises we analyse determinants of productivity. Our main empirical findings are that investment in ICT has a negative sign in different specifications of the regression but is never significant. However, the use of fax machines that gives managers access to formal information has a significant positive relationship with productivity in both countries.

description: In this paper, we assess the effect of globalization on the distribution of income within countries, focussing on the influence of foreign direct investment. We analyze data for 72 countries, 1970-90. We incorporate in our tests the Kuznets (1955) curve, measures of the character of political institutions, and various aspects of the economy and society that have been emphasized in recent research. Our results are easy to summarize. Globalization has little effect on income inequality within countries. The ratio of foreign direct investment stock to gross domestic product is unrelated to the distribution of income. Income inequality in developing and developed countries is unaffected by the presence of multinational corporations. Nor are alternative measures of economic openness - the trade-to-GDP ratio and Sachs and Warner's (1995) measure of free trade policy - associated with greater inequality. The share of income received by the poorest 20% of society in particular is not influenced by the economic importance of foreign investment. If foreign investment increases average incomes in developing countries, as we confirm here, and does not affect the distribution of income, it must benefit all segments of society in developing countries.
DEMOCRACY AND ETHNO-RELIGIOUS CONFLICT IN IRAQ

description: How can an escalation of tensions between the major ethno-religious groups be avoided in a democratizing Iraq? The first section explains why and under which conditions democratization may stir up, rather than palliate ethnic conflicts: when networks of civil society organizations have not yet developed and if the state is too weak and poor to be able to treat all citizens equally. The second section looks at the political history of Iraq, which is characterized by increasing fragmentation and conflict along ethnic lines. Pan-Arabism became the official state ideology and Shii, Kurds, Jews and Christians were excluded from positions of power and gradually driven out of the officers corps and the higher ranks of the administration. This Arabization of the Iraqi state was contested right from the beginning, as a review of the history of Kurdish and Shii uprisings will show. Throughout this history, the divisions along ethno-religious lines have deepened. Cross-ethnic parties (such as the Communists) and organizations have split along these lines too. Rising levels of repression increasingly directed against the civilian population have further estranged Kurds, Shiis and Christians from the Iraqi state and bolstered support for their respective ethno-religious organizations. Elections are likely to stir up ethno-religious conflicts in the future, if democratic institutions are not designed to foster moderation and compromise. Several such designs are discussed in the last section and the following will be recommended: an electoral system that favors vote pooling across ethnic lines; federalism on a non-ethnic basis with a strong component of fiscal decentralization; a strong regime of minority rights and a judicial apparatus capable of enforcing the rule of law. Elections should come last, not first in the process of institutional transformation. International institutions can provide the legitimacy for the continued outside supervision and support that are needed, during years to come, to make democracy sustainable.

description: This paper focuses on the interactions between local communities having at least some degree of informal claims over natural resources and external agents, particularly firms interested in commercial resource exploitation. The paper makes three contributions to the existing literature. First, unlike the literature on devolution and communal resource management, rather than concentrating on intra-community decisions, we extend the analysis to examine interactions between the community and outside agents. Second, unlike both the literature on conflict and bargaining, we integrate these two strands of the literature, so that we can endogenously derive the conditions under which community-firm interactions result in conflict or, alternatively, in bargaining agreements. Third, to the best of our knowledge, this is the first study that formally models the endogenous participation by third parties that may attempt to support communities in the process. We show that, in a context of weak property rights, improvements in the community's bargaining power vis-á-vis the firm are likely to increase resource extraction and thereby harm the environment. Moreover, an increase in the wage rate may increase or decrease resource extraction depending on initial conditions.

description: We investigate the tunneling conductance of superconductor-insulator-normal metal (SIN) and superconductor-insulator-superconductor (SIS) heterostructures with one superconducting side of the junction that is electrically driven and can exhibit $π$-pairing through a modification of the surface inversion asymmetric couplings. In SIN tunneling we find that the variation of the electrically driven interactions generally brings an increase of quasi-particles in the gap due to orbitally polarized depaired states, irrespective of the inter-band phase rearrangement. The peak of SIN conductance at the gap edge varies with a trend that depends both on the strength of the surface interactions as well as on the character of the gate-induced superconducting state. While this shift can be also associated with thermal effects in the SIN configuration, for the SIS geometry at low temperature the electric field does not yield the characteristic matching peak at voltages related with the difference between the gaps of the superconducting electrodes. This observation sets out a distinctive mark for spectroscopically distinguishing the thermal population effects from the quantum gate-driven signatures. In SIS the electrostatic gating yields a variety of features with asymmetric peaks and broadening of the conductance spectral weight. These findings indicate general qualitative trends for both SIN and SIS tunneling spectroscopy which could serve to evaluate the impact of gate-control on superconductors and the occurrence of non-centrosymmetric orbital antiphase pairing.

description: Recently, quantum simulation of low-dimensional lattice gauge theories (LGTs) has attracted many interests, which may improve our understanding of strongly correlated quantum many-body systems. Here, we propose an implementation to approximate $\mathbb{Z}_2$ LGT on superconducting quantum circuits, where the effective theory is a mixture of a LGT and a gauge-broken term. Using matrix product state based methods, both the ground state properties and quench dynamics are systematically investigated. With an increase of the transverse (electric) field, the system displays a quantum phase transition from a disordered phase to a translational symmetry breaking phase. In the ordered phase, an approximate Gauss law of the $\mathbb{Z}_2$ LGT emerges in the ground state. Moreover, to shed light on the experiments, we also study the quench dynamics, where there is a dynamical signature of the spontaneous translational symmetry breaking. The spreading of the single particle of matter degree is diffusive under the weak transverse field, while it is ballistic with small velocity for the strong field. Furthermore, due to the emergent Gauss law under the strong transverse field, the matter degree can also exhibit confinement dynamics which leads to a strong suppression of the nearest-neighbor hopping. Our results pave the way for simulating the LGT on superconducting circuits, including the quantum phase transition and quench dynamics.

THE EFFECTS OF THE DUTCH DISEASE IN RUSSIA

Year: 2004
Subjects: Political Economy

description: This paper shows how the Dutch Disease has affected the Russian economy since the start of the transition in the early 1990s. Four symptoms have been detected, namely: 1) a real exchange rate appreciation, 2) a temporary improved economic situation, 3) an output decline in the non-booming-sector, 4) an export reduction in the non-booming-sector. An extended version of the Balassa-Samuelson model has been implemented to test symptom 1. Our results suggest a positive long-run cointegration relationship between the real exchange rate and the oil price. A 7% real appreciation is caused by a 10% oil price shock. Moreover, a 10% increase in oil prices leads to a 2% GDP growth, while a 10% real appreciation is associated with a 2.1% output decline. The total effect on GDP growth, considering the Balassa-Samuelson effect, confirms symptom 2. Finally, the domestic industrial production drops and high-tech and textile exports are crowed out. This indicates that the Russian economy is also affected by symptoms 3 and 4. We conclude that Russia's government should invest the tax revenues collected from the resource sector such that the structure of the economy becomes more diversified and less vulnerable to exogenous shocks.

description: The semileptonic decays $τ^- \to μ^- M (M=π^0,η,η')$ could be sensitive probe for new physics scenarios with lepton flavor violation(LFV). Motivated by the recent Belle measurement, we investigate these decays in type III two-Higgs-doublet model (2HDM III), R-parity violating supersymmetric models(RPV SUSY) and flavor changing $Z'$ models with family non-universal couplings, respectively. In these new physics scenarios, there are LFV couplings at tree level. Our results have shown that the decays are very sensitive to the LFV couplings and could be enhanced to the present experimental sensitivities. We have derived strong bounds on relevant couplings of these models, which may be useful for further relevant studies.

description: Crystallography typically studies collections of point particles whose interaction forces are the gradient of a potential. Lifting this assumption generically gives rise in the continuum limit to a form of elasticity with additional moduli known as odd elasticity. We show that such odd elastic moduli modify the strain induced by topological defects and their interactions, even reversing the stability of, otherwise, bound dislocation pairs. Beyond continuum theory, isolated dislocations can self propel via microscopic work cycles active at their cores that compete with conventional Peach-Koehler forces caused, for example, by an ambient torque density. We perform molecular dynamics simulations isolating active plastic processes and discuss their experimental relevance to solids composed of spinning particles, vortex-like objects, and robotic metamaterials.

description: In 1996 the Tanzanian government initiated community health insurance schemes to improve the access to health care and to protect people against the financial cost of illness in an environment with shrinking budgets for the health sector. This study aims to evaluate the role of the community health funds (CHF) in lowering the barriers to access health care. Three important results emerge from this study: First, the results show that income is amongst the most important factors determining household participation in the schemes. This means that despite exemption mechanisms, the poorest of the poor within the society are not reached as they can not afford to pay regular insurance premiums. Secondly, though we find no significant differences between members and non-members in the overall amount of health expenditure and in the use of preventive measures, sick individuals in member households were 15 percentage points more likely to get treatment than those in non-member households. Hence, being insured leads to an increase in the effective demand for health care. Third, the analysis reveals that members of the CHF are better financially protected against health shocks than non members. The result of this work provides further evidence of the important role that micro insurance schemes can play in the risk management of people in developing countries.

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: Motivated by the statistical evaluation of complex computer models, we deal with the issue of objective prior specification for the parameters of Gaussian processes. In particular, we derive the Jeffreys-rule, independence Jeffreys and reference priors for this situation, and prove that the resulting posterior distributions are proper under a quite general set of conditions. A proper flat prior strategy, based on maximum likelihood estimates, is also considered, and all priors are then compared on the grounds of the frequentist properties of the ensuing Bayesian procedures. Computational issues are also addressed in the paper, and we illustrate the proposed solutions by means of an example taken from the field of complex computer model validation.

By considering a constant electric field pointing down the compact dimension, we compute the quantum effective action by integrating out the scalar degrees of freedom in the Euclidean sector. Working in the saddle-point approximation we uncover two novel branches/physical regimes upon analytically continuing back to real time and discover a new result, hitherto unreported in previous literature. Implications of our results are discussed.

description: Modern quantum experiments provide examples of transport with non-commuting quantities, offering a tool to understand the interplay between thermal and quantum effects. Here we set forth a theory for non-Abelian transport in the linear response regime. Our key insight is to use generalized Gibbs ensembles with non-commuting charges as the basic building blocks and strict charge-preserving unitaries in a collisional setup. The linear response framework is then built using a collisional model between two reservoirs. We show that the transport coefficients obey Onsager reciprocity. Moreover, we find that quantum coherence, associated to the non-commutativity, acts so as to reduce the net entropy production, when compared to the case of commuting transport. This therefore provides a clear connection between quantum coherent transport and dissipation. As an example, we study heat and squeezing fluxes in bosonic systems, characterizing a set of thermosqueezing coefficients with potential applications in metrology and heat-to-work conversion in the quantum regime.

We show that in the particle representation the vacuum can be written in a simple diagonal form. The vacuum state can describe the stationary N-particle ground state of a condensate in a trap, but it can also represent a dynamical state when, for example, a Bose-Einstein condensate initially prepared in the stationary ground state is subject to a time-dependent perturbation. In both cases the diagonal form of the Bogoliubov vacuum can be obtained by basically diagonalizing the reduced single particle density matrix of the vacuum. We compare N-body states obtained within the Bogoliubov theory with the exact ground states in a 3-site Bose-Hubbard model. In this example, the Bogoliubov theory fails to accurately describe the stationary ground state in the limit when N goes to infinity but a small fraction of depleted particles is kept constant.

description: In this paper we introduce and describe an implementation of curved (surface) geometries within the Dune framework for grid-based discretizations. Therefore, we employ the abstraction of geometries as local-functions bound to a grid element, and the abstraction of a grid as connectivity of elements together with a grid-function that can be localized to the elements to provide element local parametrizations of the curved surface.

description: We report theoretical and experimental results on the transition metal pnictide WP. The theoretical outcomes based on tight-binding calculations and density functional theory indicate that WP is a three-dimensional superconductor with an anisotropic electronic structure and nonsymmorphic symmetries. On the other hand, magnetoresistance experimental data and the analysis of superconducting fluctuations of the conductivity in external magnetic field indicate a weakly anisotropic three-dimensional superconducting phase.

title: Governmental Business Model Innovation: Multi Stakeholder Collaborations in Ecosystems
Creators: name: Alhyari, Arwa
Publisher: name: University of Kent
Year: 2024

description: Governmental critical response to future challenges and providing new solutions of improved public value creation form the bases of government innovation. While several studies can be found on different forms of public sector innovation, research on governmental business model innovation is still limited. In this area, public and private multi stakeholder collaborations are establishing a new approach of collaborative innovation involving governmental organisations in multi actor networks and ecosystems. However, it is not yet clear how governmental organisations innovate their collaborative business models through multi stakeholder collaborations in ecosystems to create value. Understanding how these collaborations are driving the growth of ecosystems have important gains to the field of management. A multiple case study research strategy was adopted to enable developing theory and in depth understanding of the governmental business model innovation in a complex setting of multi stakeholder's collaborations in ecosystems. This research provides original contributions to the management literature by expanding the understanding of BMI concept, and introducing a new government innovation form by the revealed Collaboration Business Model Innovation (Co-BMI) which offers a novel process model for how managers of governmental organizations innovate their business in collaborations with multi stakeholders. The research set forward important implications supporting the ongoing efforts for developing the ecosystem theory through the uncovered value based structure; the Ecosystem Value Structure (EVS) which delivers a novel approach for managing ecosystems that can fit varying contexts. Guided by the revealed Collaboration Business Model Innovation (Co-BMI), managers will have a strategic tool enabling them to apply innovative business models that improve public value creation in multi stakeholder collaborations. Whereas the Ecosystem Value Structure (EVS) model and the revealed insightful ecosystem governance factors will provide governmental organizations and businesses with a managerial road map for how to manage the entire ecosystem prosperously.

description: A large body of literature suggests individuals behave differently when responding to hypothetical valuation questions than when actual payment is required. Such findings have generated a great deal of skepticism over the use of the contingent valuation method and benefit measures derived from it. Recently, a new method, cheap talk, has been proposed to eliminate the potential bias in hypothetical valuation questions. Cheap talk refers to process of explaining hypothetical bias to individuals prior to asking a valuation question. This study explores the effect of cheap talk in a mass mail survey using a conventional value elicitation technique. Results suggest that cheap talk was effective at reducing willingness-to-pay for most survey participants. However, consistent with previous research, cheap talk did not reduce willingness-to-pay for consumers who were knowledgeable of the good evaluated.
Gauge-invariant Non-spherical Metric Perturbations of Schwarzschild Black-Hole Spacetimes

description: The theory of gauge-invariant non-spherical metric perturbations of Schwarzschild black hole spacetimes is now well established. Yet, as different notations and conventions have been used throughout the years, the literature on the subject is often confusing and sometimes confused. The purpose of this paper is to review and collect the relevant expressions related to the Regge-Wheeler and Zerilli equations for the odd and even-parity perturbations of a Schwarzschild spacetime. Special attention is paid to the form they assume in the presence of matter-sources and, for the two most popular conventions in the literature, to the asymptotic expressions and gravitational-wave amplitudes. Besides pointing out some inconsistencies in the literature, the expressions collected here could serve as a quick reference for the calculation of the perturbations of Schwarzschild black hole spacetimes driven by generic sources and for those approaches in which gravitational waves are extracted from numerically generated spacetimes.

description: This paper presents the first active object mapping framework for complex robotic manipulation and autonomous perception tasks. The framework is built on an object SLAM system integrated with a simultaneous multi-object pose estimation process that is optimized for robotic grasping. Aiming to reduce the observation uncertainty on target objects and increase their pose estimation accuracy, we also design an object-driven exploration strategy to guide the object mapping process, enabling autonomous mapping and high-level perception. Combining the mapping module and the exploration strategy, an accurate object map that is compatible with robotic grasping can be generated. Additionally, quantitative evaluations also indicate that the proposed framework has a very high mapping accuracy. Experiments with manipulation (including object grasping and placement) and augmented reality significantly demonstrate the effectiveness and advantages of our proposed framework.

description: This paper uses data from dairy farmers in six U.S. states to examine farm-level factors influencing the adoption of recombinant bovine somatatropin (rBST), a productivity-enhancing hormone that is injected in cows. The results of multinomial logit estimations of rBST adoption and disadoption show that herd size, education, and complementary technologies all play positive and important roles in rBST adoption.
SU(6) Extension of the Weinberg-Tomozawa Meson-Baryon Lagrangian

description: A consistent SU(6) extension of the Weinberg-Tomozawa meson-baryon chiral Lagrangian is constructed which incorporates vector meson and baryon decuplet degrees of freedom. The corresponding Bethe-Salpeter approximation predicts the existence of an isoscalar spin-parity ${3/2}^-$ $K^*N$ bound state (strangeness +1) with a mass around 1.7--1.8$ $GeV. It is the highest hypercharge state of an antidecuplet SU(3) representation and it is unstable through $K^*$ decay. The estimated width of this state (neglecting d-wave $KN$ decay) turns out to be small ($Γ\le 15 $MeV). Clear signals of this resonance would be found in reactions like $γp \to {\bar K}^0 p K^+ π^-$ by looking at the three body $p K^+ π^-$ invariant mass.

Search for heavy resonances decaying into a pair of $Z$ bosons in the $\ell^+\ell^-\ell'^+\ell'^-$ and $\ell^+\ell^-ν\barν$ final states using 139 fb$^{-1}$ of proton-proton collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector

description: A search for heavy resonances decaying into a pair of $Z$ bosons leading to $\ell^+\ell^-\ell'^+\ell'^-$ and $\ell^+\ell^-ν\barν$ final states, where $\ell$ stands for either an electron or a muon, is presented. The search uses proton-proton collision data at a centre-of-mass energy of 13 TeV collected from 2015 to 2018 that corresponds to the full integrated luminosity of 139 fb$^{-1}$ recorded by the ATLAS detector during Run 2 of the Large Hadron Collider. Different mass ranges spanning 200 GeV to 2000 GeV for the hypothetical resonances are considered, depending on the final state and model. In the absence of a significant observed excess, the results are interpreted as upper limits on the production cross section of a spin-0 or spin-2 resonance. The upper limits for the spin-0 resonance are translated to exclusion contours in the context of Type-I and Type-II two-Higgs-doublet models, and the limits for the spin-2 resonance are used to constrain the Randall--Sundrum model with an extra dimension giving rise to spin-2 graviton excitations.
