Search for the production of Dark Matter in hadronic mono-top signatures with the CMS experiment
Creators: name: Waßmer, Michael
Publisher: name: Karlsruher Institut für Technologie (KIT)
Year: 2021

description: A search for the production of Dark Matter in hadronic mono-top signatures using data recorded by the CMS experiment in the years from 2016 to 2018 is presented. First, the analysis strategy is defined relying on the existence of large missing transverse momentum and a large-radius jet. The underlying theoretical model is then studied in order to validate the analysis strategy. Consequently, the modeling of the production of single vector bosons in association with additional jets is studied in detail because of its importance regarding the background model of this analysis. Corrections based on available state-of-the-art theoretical calculations are derived in order to improve the modeling of the aforementioned processes and these corrections are compared to alternative corrections based on Monte Carlo simulation. Next, the data analysis and its technical details are explained. Then, a statistical model is built estimating the major background processes utilizing data from control regions. Finally, a statistical hypothesis test combined with parameter estimation is performed in order to search for possible signal contributions in data. No significant signal contributions were found. Therefore, parameter ranges of the used theoretical signal model were excluded.

description: Transfer reactions provide information about the single-particle nature of nuclear levels. In particular, the differential cross sections from these measurements are sensitive to the angular momentum of the transferred particle and the spectroscopic factor of the populated level. However, the process of extracting these properties is subject to uncertainties, both from experimental and theoretical sources. By integrating the distorted wave Born approximation into a Bayesian model, we propagate these uncertainties through to the spectroscopic factors and orbital angular momentum values. We use previously reported data of the proton pickup reaction $^{70}$Zn$(d, ^3\!\text{He}) ^{69}$Cu as an example. By accounting for uncertainties in the experimental data, optical model parameters, and reaction mechanism, we find that the extracted spectroscopic factors for low lying states of $^{69}$Cu are subject to large, asymmetric uncertainties ranging from $35 \%$ to $108 \%$. Additionally, Bayesian model comparison is employed to assign probabilities to each of the allowed angular momentum transfers. This method confirms the assignments for many states, but suggests that the data for a state lying at $3.70$ MeV is better characterized by an $\ell = 3$ transfer, rather than the previously reported $\ell = 2$.

description: Mongolia, unlike several other Asian Transitional economies, has since 1990 pursued a "Russian-style" transition to a market economy. This has entailed rapid and extensive privatisation accompanied by, inter alia, stabilisation, liberalisation and de-regulation. The transition process has been characterised by relatively poor macroeconomic performance and increased levels of poverty and inequality in income distribution. Privatisation had the central objective of cementing the new political and economic framework, and little consideration was given to issues of competition and regulation. Proposed privatisations in the social sector, infrastructure and land increase the urgency with which these issues must be addressed. In this paper, we briefly describe the chief features of Mongolia's transition and of the privatisations that accompanied and, to a degree, defined it. We identify a range of issues relating to regulation and discuss the degree to which they are being addressed by the post-1990 political class. We conclude that although there exist, or that there are plans to establish, a number of regulatory agencies, nevertheless there is a lack of political commitment to implementation and enforcement. There is also little official recognition and appreciation of the extent, depth and implications of market failure. The scarcity of experienced and technically competent staff capable of establishing and operating effective regulatory agencies and ensuring compliance is a major problem. It is possible that regulatory capture is already a significant problem in key sectors of the economy.

description: It has been cross-culturally documented that women exhibit a preference for mateswho possess resources or traits that signal potential wealth. The majority of thisliterature relies on self reported mate preferences. Here we report on twoexperiments to test whether women’s willingness to date men is actually influencedby their perceived wealth. Online dating profiles were created to presentphotographs of men and information about their current bank account status (Study1), or to indirectly indicate their level of wealth (Study 2). In Study 1, the faces werepresented with alternating high and low bank account balances. We hypothesizedthat women who viewed men with high bank account values would evaluate them asmore desirable than women who viewed men with low bank account values. That is,they would be more likely to engage with him in an online conversation, meet withhim for a casual coffee, accept an invitation of a date, consider him for a one-nightstand, consider him for a short-term relationship, or consider him for a long-termrelationship. It was also hypothesized that women would rate the men with highbank account balances as more physically attractive than the men with the low bankaccount balances. The results generally do not support the hypotheses. In Study 2,we replaced bank account balances with indirect indicators of wealth. Our resultsindicate that women were significantly less interested in wealthier men as comparedto poorer men, possibly because the wealthy men may be perceived as bragging.Together, these studies suggest men’s wealth may not be as important to women ashas been previously considered, but further research is needed.

description: We examine the spatial distribution of electrons generated by a fixed energy point source in uniform, parallel electric and magnetic fields. This problem is simple enough to permit analytic quantum and semiclassical solution, and it harbors a rich set of features which find their interpretation in the unusual and interesting properties of the classical motion of the electrons: For instance, the number of interfering trajectories can be adjusted in this system, and the turning surfaces of classical motion contain a complex array of singularities. We perform a comprehensive analysis of both the semiclassical approximation and the quantum solution, and we make predictions that should serve as a guide for future photodetachment experiments.

This is explicated through exact cnoidal wave and localized soliton solutions of the MKdV equation with variable coefficients. The solitons can be accelerated and their propagation can be manipulated by suitable variations of the above parameters. In sharp contrast with nonlinear Schrödinger equation, the soliton amplitude and widths are time independent.

description: It has been previously demonstrated that women who utilize the competitorderogation strategy (which requires fierce and explicit tactics to secure resources)are perceived more negatively than those who utilize the self-promoting strategy(which includes subtler tactics to secure resources). Some of these resources aredirectly related to and for the benefit of a woman’s offspring. However, it remainsunknown how women who use these strategies for accessing resources for theiroffspring are perceived by potential rivals (other females) and potential mates(males). We propose that mothers who derogate their competition (other mothers)will be seen more negatively than those who self-promote. Using a pre-post studydesign, female participants rated 12 mothers’ photographs for attractiveness,competency as a mother, and personality. In the pre-condition participants rated thewoman in the photograph, while in the post-condition the participants rated her afterbeing told the woman made a ‘Facebook post’ containing maternal competitorderogation or self-promotion. Differences in pre-post ratings were calculated, withchange presumably caused by strategy use. Results indicate women who promotetheir maternal competency via self-promotion are perceived to be less likeablecompared to baseline ratings, and women who derogate their competition areperceived less positively on the majority of attributes.

description: The aims of this paper are to explore the role of variations and commonalities in Medium-N comparative analysis and to suggest a technique that could maximize their explanatory power in the context of medium-N comparative designs, especially those designs that combine two or more comparative approaches to the study of regulatory change. The paper identifies four popular comparative approaches to the study of politics and policy in general and regulation in particular. These four might best be titled the National Patterns Approach (NPA), the Policy Sector Approach (PSA), the International Regime Approach (IRA), and the Temporal Patterns Approach (TPA). While these approaches are not necessarily contradictory they represent different assumptions as to the determinant of political and regulatory change. Each of these approaches omits some important sources of variations and commonalties in the regulation of the economy and society. To overcome these omissions it is suggested that combinations of these approaches - through complex research designs - might prove a more sound and effective method for the study of regulation.

description: The universal power law tails of single particle and multi-particle time correlation functions are derived from a unifying point of view, solely using the hydrodynamic modes of the system. The theory applies to general correlation functions, and to systems more general than classical fluids. Moreover it is argued that the collisional transfer part of the stress-stress correlation function in dense classical fluids has the same long time tail $\sim t^{-1-d/2}$ as the velocity autocorrelation function in Lorentz gases.

description: We consider reflected entropy in a thermofield double state perturbed by a heavy operator insertion. For sufficiently early operator insertions the dual geometry can be described by a localized shock wave geometry. We calculate the entanglement wedge cross-section in this geometry for symmetric intervals and find that it matches precisely with the CFT result for sufficiently late times. Our result exhibits a plateau before going to zero, a behaviour similar to the one observed recently in the context of global quantum quenches. We find that at high temperatures this behaviour is properly captured by the line-tension picture.

description: We revisit the problem of bound states in graphene under the influence of point electric monopole and dipole impurity potentials extended to the case in which the membrane of this material is uniformly and uniaxially strained, which leads to a redefinition of the charge and dipole moment, respectively. By considering an anisotropic Fermi velocity, we analytically solve the resulting Dirac equation for each potential. We observe that the effect of the anisotropy is to promote or inhibit the critical behavior known to occur for each kind of impurity, depending on the direction along which strain is applied: both the atomic collapse, for the monopole impurity, and the emergence of cascades of infinitely many bound states with a universal Efimov-like scaling, for the dipole impurity, are phenomena that occur under less or more restrictive conditions due to strain.

description: The relationship between legal tradition and competition policy is a multidimensional and complex one. Qualitative arguments on such a relationship have revolved around the evolution of competition laws in the United States and Europe and the difficulty of convergence between the two. This issue is further complicated by institutional variations in the structures and processes of competition law enforcement. Preliminary quantitative analysis based on very limited variables and data indicate that legal tradition may have very limited effects on competition law.

description: Using the UVES echelle spectrograph at the ESO VLT we obtained two-dimensional high-resolution (R = 50 000) spectra of the edge-on disk objects HH30*, HK Tau B, and HV Tau C. For comparison purposes we also observed with the same equipment both the classical T Tauri star HL Tau and the active late-type star LDN 1551-9. The spectra of all three observed edge-on disks consist of a T Tauri emission and absorption line spectrum with superimposed jet emission lines. Analysis of the spectra confirmed that the disks are completely opaque at visible wavelengths and that light from the central objects reaches us only via scattering layers above and below the disk planes. The central objects of our targets were found to be normal T Tauri stars showing moderate but different amounts of veiling of their photospheric spectra, indicating different accretion rates or evolutionary stages. We suggest that all classical T Tauri stars (CTTSs) show this observed morphology when viewed edge-on. Part of the jet emission from edge-on systems is directly visible to us in the forbidden lines as well as in Halpha and He I, a finding which contradicts the present paradigm of a pure magnetospheric accretion origin for the formation of hydrogen and helium emission lines in moderately active CTTSs. From a comparison with those Taurus-Auriga CTTSs for which the inclination is reliably known, we conclude that the view angle of CTTS systems is one of the key parameters governing apparent Halpha emission strength in the T Tauri class. We discuss the various possible formation regions for the Na I D lines and show that profiles similar to observed ones can be formed at the base of the disk wind.

Public Management and Regulatory Governance: Problems of Policy Transfer to Developing Countries

description: The focus of this paper is on the conceptual and empirical problems that arise in the analysis of the administrative and political context of economic and social regulation in developing countries. After a discussion of the significance of dominant ideas in current debates on economic and social development policy, the paper examines the main characteristics of regulatory governance in developed economies, since the privatisation and regulatory reforms recently introduced into developing economies are broadly modelled on developed country experience. It is argued that regulatory reforms need to be analysed in the broader context of the new public management (NPM) and governance reforms which have been spreading across both developed and developing systems of government in the last two decades. One reason for close attention to systems of governance is that in developing countries, the state is likely to retain greater responsibilities for economic and social regulation than is now the case in developed economies. In this event, "Western" models of regulation will not be easily emulated or transferred because of the resistant political and administrative cultures that must receive them. The forms of this "reality gap" are examined, and the implications for the reshaping of state- market relations in developing countries are considered, as well as the implications for pro-poor strategies.
The Institutional and Policy Framework for Regulation and Competition in Malaysia

Year: 2002
Subjects: Public Economics

description: Regulatory reforms took place in Malaysia mainly as a consequence of the privatization since the mid-1980s. A sectoral approach to regulation has been adopted in sectors where privatization took place. Competition regulation has only been implemented in one sector, namely the communications and multimedia sector. The government may implement a national competition policy by 2003. Economic regulation, such as control over entry-exit conditions to achieve goals related to poverty eradication and wealth redistribution, continues to be important. Some trade-off between competition and the achievement of these objectives seems imminent and unavoidable. Industrial and trade policies to protect local industries via high import duties also come into conflict with the objectives of competition regulation. Some initiatives to implement good corporate governance have been undertaken.

description: Spin crossover molecules have two accessible states: high spin (HS) and low spin (LS). We show that, on the pyrochlore lattice, elastic interactions between SCO molecules can give rise to three spin-state ice phases. Each is a ``Coulomb phase'' where a local ice-rule can be mapped to a divergence free gauge field and the low energy excitations carry a spin fractionalized midway between the LS and HS states. The unique nature of spin crossover materials allows temperature to change the ice rules allowing straightforward access to Coulomb phases not yet observed in water or spin ices.

A comparison of two hysteretic models in predicting the response of a connector under cyclic loading
Creators: name: Lo, Yvonne P. Y.
Publisher: name: University of British Columbia
Year: 2009

description: The effect of seismic loading on structures has become a main concern due to the number of collapses or incidents of substantial damage during recent earthquakes. The inelastic behavior of a fastener under seismic loading is a determinant factor of the response of the whole structure; hence, the dynamic behaviour of the fasteners is a main issue for study. The objective of this research is to compare the response of a fastener predicted by a finite-element model (HYST) and the empirical Bouc-Wen-Baber-Noori model (BNW). HYST is a mechanics-based model that uses material properties of the fastener and the characteristics of its surrounding medium to predict the response. BNW is a mathematical model involving 13 parameters. The hysteretic results calculated by this model are obtained by integration of a first order differential equation, given a displacement history A(t). The BNW parameters are calibrated using the response to a particular cyclic displacement history, and then the responses are evaluated for other different histories or seismic excitations. Results are compared to the corresponding HYST outputs. The results show that BNW gives comparable values for relative maximum displacements with respect to the medium, and restoring forces when the response of the structure remains elastic. However, the discrepancies increase with nonlinearities, and the model cannot accurately predict, for example, the residual deformations.

description: In England, over the last decade the rising incidence of bovine TB has resulted in recognised economic impacts on the agricultural and ancillary industries. Nowhere has the dramatic increase in bovine TB been more evident than in Southwest England, a region which is characterised by smaller, family-run farms often specialising in relatively extensive bovine livestock systems, whether dairying or beef production. The economic impacts result from the nature of the disease, the government's control measures (restrictions on movement of cattle on and off the farm, repeat testing and compulsory cleaning) and the impact of test 'failures' on the normal marketing of livestock and product. Moreover, this worsening of the disease situation - and hence increasing economic impact - of bovine TB coincides with a period of considerable economic pressures for the agricultural industry. Principal among these are (a) the recent major changes in the CAP, (b) established long-term changes in the food chain (many of which are detrimental to primary producers), (c) new requirements for an increasingly environmentally-friendly farming systems and (d) increased competitive pressures from the enlargement of the EU and greater exposure to global markets. In conjunction with the farming industry, the veterinary profession and other stakeholders, the government is currently developing a new strategy for tackling bovine TB. Bovine TB is acknowledged as one of the most difficult animal health problems facing UK farmers with the incidence now rising at 18 per cent each year. A further factor of particular relevance is the government's recent Animal Health and Welfare Strategy and its implications for affected herds. There is no scientific consensus about why the incidence of bovine TB is rising again (having apparently been brought under reasonable control by the 1970s), although there is increasing scientific evidence of a reservoir of infection in wildlife, particularly in badgers.
Polar Polytopes and Recovery of Sparse Representations

description: Suppose we have a signal y which we wish to represent using a linear combination of a number of basis atoms a_i, y=sum_i x_i a_i = Ax. The problem of finding the minimum L0 norm representation for y is a hard problem. The Basis Pursuit (BP) approach proposes to find the minimum L1 norm representation instead, which corresponds to a linear program (LP) that can be solved using modern LP techniques, and several recent authors have given conditions for the BP (minimum L1 norm) and sparse (minimum L0 solutions) representations to be identical. In this paper, we explore this sparse representation problem} using the geometry of convex polytopes, as recently introduced into the field by Donoho. By considering the dual LP we find that the so-called polar polytope P of the centrally-symmetric polytope P whose vertices are the atom pairs +-a_i is particularly helpful in providing us with geometrical insight into optimality conditions given by Fuchs and Tropp for non-unit-norm atom sets. In exploring this geometry we are able to tighten some of these earlier results, showing for example that the Fuchs condition is both necessary and sufficient for L1-unique-optimality, and that there are situations where Orthogonal Matching Pursuit (OMP) can eventually find all L1-unique-optimal solutions with m nonzeros even if ERC fails for m, if allowed to run for more than m steps.

description: It is a well-known result due to E. Størmer that every positive qubit map is decomposable into a sum of a completely positive map and a completely copositive map. Here, we generalize this result to tensor squares of qubit maps. Specifically, we show that any positive tensor product of a qubit map with itself is decomposable. This solves a recent conjecture by S. Fillipov and K. Magadov. We contrast this result with examples of non-decomposable positive maps arising as the tensor product of two distinct qubit maps or as the tensor square of a decomposable map from a qubit to a ququart. To show our main result, we reduce the problem to Pauli diagonal maps. We then characterize the cone of decomposable ququart Pauli diagonal maps by determining all 252 extremal rays of ququart Pauli diagonal maps that are both completely positive and completely copositive. These extremal rays split into three disjoint orbits under a natural symmetry group, and two of these orbits contain only entanglement breaking maps. Finally, we develop a general combinatorial method to determine the extremal rays of Pauli diagonal maps that are both completely positive and completely copositive between multi-qubit systems using the ordered spectra of their Choi matrices. Classifying these extremal rays beyond ququarts is left as an open problem.

description: We describe the effects of weak gravitational lensing by cosmological large scale structure on the diffuse emission of 21 centimeter radiation from neutral hydrogen at high redshifts during the era of reionization. The ability to observe radial information through the frequency, and thus three-dimensional regions of the background radiation at different redshifts, suggests that 21 cm studies may provide a useful context for studying weak lensing effects. We focus on the gravitational lensing effects on both the angular power spectra and the intrinsic, three-dimensional power spectra. We present a new approach for calculating the weak lensing signature based on integrating differential Fourier-space shells of the deflection field and approximating the magnification matrix. This method is applied to reionization models of the 21 cm spectra up to small angular scales over a range in redshift. The effect on the angular power spectrum is typically < 1% on small angular scales, and very small on scales corresponding to the feature imprinted by reionization bubbles, due to the near-scale invariance of the angular power spectrum of the 21 cm signal on these scales. We describe the expected effect of weak lensing on three-dimensional 21 cm power spectra, and show that lensing creates aspherical perturbations to the intrinsic power spectrum which depend on the polar angle of the wavevector. The effect on the 3D power spectrum is < 1% on scales k < 0.1 h/Mpc, but can be > 1% for highly inclined modes for k > 1 h/Mpc. The angular variation of the lensing effect on these scales is well described by a quartic polynomial in the cosine of the polar angle. The detection of the gravitational lensing effects on 21 cm power spectra will require very sensitive, high resolution observations by future low-frequency radio arrays.

description: An algebraic analysis of Grover's quantum search algorithm is presented for the case in which the initial state is an arbitrary pure quantum state of n qubits. This approach reveals the geometrical structure of the quantum search process, which turns out to be confined to a four-dimensional subspace of the Hilbert space. This work unifies and generalizes earlier results on the time evolution of the amplitudes during the quantum search, the optimal number of iterations and the success probability. Furthermore, it enables a direct generalization to the case in which the initial state is a mixed state, providing an exact formula for the success probability.

description: The designation of Exmoor National Park in 1954 recognised the importance of the open character of much of the area and, in particular, its moorland to that natural heritage of the UK. However, the moorland that the park was charged with maintaining and enhancing was soon under threat and the following years saw extensive moorland loss and the fragmentation of remaining moorland (Lowe et al, 1986). The ensuing moorland conflict and debate eventually lead Exmoor NPA, in collaboration with farmers, land owners, the CLA and NFU to pioneer a new system of moorland management agreements. Indeed, for a short time, Exmoor was the only location operating wholly voluntary management agreements (Brotherton, 1990). Only two agreements now remain and in the twenty-five years since their inception much has changed. Once castigated for their "theft of the countryside" (Shoard, 1980), many farmers now work in partnership with statutory and non-statutory organisations as 'stewards' of the countryside. The purpose of this chapter is to review the policy and economic changes affecting farming over this time and to review the development of Exmoor moorland management agreements.
Multiple time scales and the exponential Ornstein-Uhlenbeck stochastic volatility model

description: We study the exponential Ornstein-Uhlenbeck stochastic volatility model and observe that the model shows a multiscale behavior in the volatility autocorrelation. It also exhibits a leverage correlation and a probability profile for the stationary volatility which are consistent with market observations. All these features make the model quite appealing since it appears to be more complete than other stochastic volatility models also based on a two-dimensional diffusion. We finally present an approximate solution for the return probability density designed to capture the kurtosis and skewness effects.

Starbursting Nuclei in Old Dwarf Galaxies

description: Nuclei of early-type dwarf galaxies (dEs) are usually younger than the galaxy main body, and such discrepancy in age has been a puzzle. To explore the origin of young nuclei in dEs, we study a sample of dEs having compact star-forming blobs that are visually similar to dEs' nuclei but by far bluer. We find that (1) the compact star-forming blobs have a typical stellar mass of one percent of the host galaxy stellar mass; (2) some of the blobs are positioned slightly off from the center of the galaxies; (3) the H$α$ equivalent width measured from the publicly available Sloan Digital Sky Survey fiber spectroscopy shows their formation ages being an order of few Mega-year; and (4) their emission line metallicities, 12\,+\,log(O/H), are as high as the solar value, while the underlying galaxies have the typical stellar populations of dEs, i.e., log(Z/Z$_{\sun}$)\,$\sim$\,$-0.8$. Based on the results, we argue that the central star-forming blobs can provide a caught-in-the-act view of nuclei formation in dEs, and discussing possible formation mechanisms of young nuclei in old dEs. We particularly propose that these off-centered compact star-forming regions may act as seeds of nuclei as proposed in the `wet migration' scenario of \cite{Guillard16}.
