description: In this article we define Lagrangian concordance of Legendrian knots, the analogue of smooth concordance of knots in the Legendrian category. In particular we study the relation of Lagrangian concordance under Legendrian isotopy. The focus is primarily on the algebraic aspects of the problem. We study the behavior of the classical invariants under this relation, namely the Thurston-Bennequin number and the rotation number, and we provide some examples of non-trivial Legendrian knots bounding Lagrangian surfaces in $D^4$. Using these examples, we are able to provide a new proof of the local Thom conjecture.

description: This thesis investigates the effects of air passengers' and travel intermediaries' expectations on their beliefs, attitude and behavioural intentions. I develop a conceptual model articulating the nature and antecedents of three types of expectations: would, could and should. I propose that would and should expectations influence updated beliefs through attitude towards news for two different stakeholder groups and that would expectations mediate the relationship between could expectations and attitude towards news for two different stakeholder groups. Empirically, I measure prior dispositions and intentions, then how beliefs, attitude and behavioural intentions change towards a focal airline in response to a piece of corporate social responsibility (CSR) news about it. 781 airline passenger stakeholders (B2C) and 356 travel intermediaries (B2B) were surveyed after an initial pre-test of the survey instrument and a pilot study. Structural equation models (SEM) and multi-group structural equation models (multi-group SEM) largely provided support for the hypothesised model.

description: Brillouin imaging relies on the reliable extraction of subtle spectral information from hyperspectral datasets. To date, the mainstream practice has been using line fitting of spectral features to retrieve the average peak shift and linewidth parameters. Good results, however, depend heavily on sufficient SNR and may not be applicable in complex samples that consist of spectral mixtures. In this work, we thus propose the use of various multivariate algorithms that can be used to perform supervised or unsupervised analysis of the hyperspectral data, with which we explore advanced image analysis applications, namely unmixing, classification and segmentation in a phantom and live cells. The resulting images are shown to provide more contrast and detail, and obtained on a timescale $10^2$ faster than fitting. The estimated spectral parameters are consistent with those calculated from pure fitting.

description: Twenty years on from the publication of Stephen Skowronek's seminal work The Politics Presidents Make, the concept of political time developed within it remains both a fascinating and under-utilized framework for understanding political leadership. Political time provides a functional and thought-provoking alternative perspective to individual-centric accounts of leadership and change. By examining context, ideas and historical opportunities Skowronek offers unique insights into why presidents succeeded or failed as agents of change within their political environment. Yet despite being widely praised, Skowronek's theories have failed to develop in many key areas and have not influenced the broader leadership research agenda as it was hoped. This thesis aims to stimulate interest in Skowronek's work through its exploration of three major areas of underdevelopment in political time theory. Firstly, by examining its application in other political contexts both theoretically and empirically using Australia as the primary case study. Secondly, by exploring its relevance to contemporary presidential politics in the United States and revisiting the 'waning of political time' hypothesis that was developed in the original book, with reference to the contemporary presidencies of Ronald Reagan and Barack Obama. And finally, by rethinking some of its precepts which have hampered its explanatory power and attracted the bulk of criticism. These theoretical ideas are explored empirically by re-examining the case of the 1890s in American politics, and providing new ways through which to interpret it. This thesis makes the case that Skowronek's magnum opus is far more than just an interesting intellectual exercise. On the contrary, political time is both heuristically and explanatorily useful to the study of leadership and has great potential to keep pace with contemporary developments, and through theoretical and empirical development it can provide new answers to old questions. - provided by Candidate.

description: The generalized stacking fault (SFE) energy curves of pure gold (Au) and its binary alloys with transition metals are determined from density functional theory (DFT). Alloy elements Ag, Al, Cu, Ni, Ti, Zr, Zn, In, Ga, Sn, Mn, Cd, Sn, Ta and Cr are substituted into Au at concentrations up to 4%. A comparison of various proposed methodologies to calculate SFEs is given. The intrinsic SFE decreases for all alloying elements from its value for pure Au, but SFE energies (both stable and unstable) vary strongly with the distance of the alloying element from the stacking fault region, and with alloy concentration. The compositional dependence of the SFE on the volume change associated with alloying element is determined. This work demonstrates that the SFE is strongly influenced by misfit strain caused by the alloying elements. Moreover, the computed generalized SFE curves provide information valuable to developing an understanding of the deformation behavior of Au and Au-alloys.

description: In this study we present first results from a new detector of UV photons: a thick gaseous electron multiplier (GEM) with resistive electrodes, combined with CsI or CsTe/CsI photocathodes. The hole type structure considerably suppresses the photon and ion feedback, whereas the resistive electrodes protect the detector and the readout electronics from damage by any eventual discharges. This device reaches higher gains than a previously developed photosensitive RPC and could be used not only for the imaging of UV sources, flames or Cherenkov light, for example, but also for the detection of X-rays and charged particles.

description: NGC1052-DF2 and NGC1052-DF4 are ultra-diffuse galaxies (UDGs) that were found to have extremely low velocity dispersions, indicating that they have little or no dark matter. Both galaxies host anomalously luminous globular cluster (GC) systems, with a peak magnitude of their GC luminosity function (GCLF) that is $\sim1.5$ magnitudes brighter than the near-universal value of $M_V \approx -7.5$. Here we present an analysis of the joint GCLF of the two galaxies, making use of new HST photometry and Keck spectroscopy, and a recently improved distance measurement. We apply a homogeneous photometric selection method to the combined GC sample of DF2 and DF4. The new analysis shows that the peak of the combined GC luminosity function remains at $M_V \approx -9$ mag. In addition, we find a subpopulation of less luminous GCs at $M_V \approx -7.5$ mag, where the near-universal GCLF peak is located. The number of GCs in the magnitude range of $-5$ to $-8$ is $7.1_{-4.34}^{+7.33}$ in DF2 and $8.6_{-4.83}^{+7.74}$ in DF4, similar to that expected from other galaxies of the same luminosity. The total GC number between $M_V$ of $-5$ to $-11$ is $18.5_{-4.42}^{+8.99}$ for DF2 and $18.6_{-4.92}^{+9.37}$ for DF4, calculated from the background-subtracted GCLF. The updated total number of GCs in both galaxies is $37^{+11.08}_{-6.54}$. The number of GCs do not scale with the halo mass in either DF2 or DF4, suggesting that $N_{GC}$ is not directly determined by the merging of halos.

Dwelling densification and "greenness": Hong Kong’s high-density housing and resource conservation
Creators: name: Wong, Kam Sing
Publisher: name: University of British Columbia
Year: 2009

description: Urban dwelling densities have profound implications on the form of built environment, which in turn incurs significant effects on the patterns of resource use associated with housing construction and operational needs. Hong Kong is a compact, industrialized city with housing at very high densities. This thesis proposes and tests the hypothesis that Hong Kong's housing represents a green model of residential development which is conducive to low per capita consumption. Reducing per capita consumption is a primary greening agenda, especially for industrialized regions. "Wastes" are also increasingly seen as resources. This thesis addresses three aspects of resource use: energy, water (including "wastewater"), and materials (including solid "waste"). Hong Kong's housing development is commonly in the form of estates which are characterized by large site area measured in hectares and towers of 30-40 storeys. The current densities are 2000- 4000 residents per hectare of net site area, plot ratio of 5 and above, 1-2 square metres of communal open space per resident, and 15-20 square metres of gross floor area per resident. In contrast, the corresponding densities of North American single-family dwelling are 50-100 residents per hectare of net site area, plot ratio of less than 1, about 100 square metres of private open space per resident, and 80-100 square metres of floor area per resident. The analysis offered in this thesis shows that Hong Kong's dwelling densification is conducive to efficient centralized systems such as mass transit, sea-water flushing, and inorganic waste segregation — which consequently lead to low per capita consumption of fossil fuels and potable water and high per capita recovery of domestic solid waste. On a building level, the attached, compact dwelling configuration also leads to low per capita energy and material use associated with housing construction. However, very high "building densities" entail physical/spatial constraints on a number of greening practices, such as harnessing of ambient wind for space cooling and on-site recovery of wastewater and organic waste. A direction towards high "occupancy density" in company with moderate "building density" should be considered as a greener housing alternative in long term.

For the glueball mass in the region 1.5-1.7 GeV, the model predicts on average (per event) 0.5-1.5 glueballs at RHIC and 1.5-4 glueballs at LHC energies. Possible enhancement mechanisms are discussed.

description: We present a study of six open clusters (Berkeley 67, King 2, NGC 2420, NGC 2477, NGC 2682 and NGC 6940) using the Ultra Violet Imaging Telescope (UVIT) aboard \textit{ASTROSAT} and \textit{Gaia} EDR3. We used combinations of astrometric, photometric and systematic parameters to train and supervise a machine learning algorithm along with a Gaussian mixture model for the determination of cluster membership. This technique is robust, reproducible and versatile in various cluster environments. In this study, the \textit{Gaia} EDR3 membership catalogues are provided along with classification of the stars as \texttt{members, candidates} and \texttt{field} in the six clusters. We could detect 200--2500 additional members using our method with respect to previous studies, which helped estimate mean space velocities, distances, number of members and core radii. UVIT photometric catalogues, which include blue stragglers, main-sequence and red giants are also provided. From UV--Optical colour-magnitude diagrams, we found that majority of the sources in NGC 2682 and a few in NGC 2420, NGC 2477 and NGC 6940 showed excess UV flux. NGC 2682 images have ten white dwarf detection in far-UV. The far-UV and near-UV images of the massive cluster NGC 2477 have 92 and 576 \texttt{members} respectively, which will be useful to study the UV properties of stars in the extended turn-off and in various evolutionary stages from main-sequence to red clump. Future studies will carry out panchromatic and spectroscopic analysis of noteworthy members detected in this study.

description: GRB 041006 was detected by HETE-2 at 12:18:08 UT on 06 October 2004. This GRB displays a soft X-ray emission, a precursor before the onset of the main event, and also a soft X-ray tail after the end of the main peak. The light curves in four different energy bands display different features; At higher energy bands several peaks are seen in the light curve, while at lower energy bands a single broader bump dominates. It is expected that these different features are the result of a mixture of several components each of which has different energetics and variability. To reveal the nature of each component, we analysed the time resolved spectra and they are successfully resolved into several components. We also found that these components can be classified into two distinct classes; One is a component which has an exponential decay of $E_{p}$ with a characteristic timescale shorter than $\sim$ 30 sec, and its spectrum is well represented by a broken power law function, which is frequently observed in many prompt GRB emissions, so it should have an internal-shock origin. Another is a component whose $E_{p}$ is almost unchanged with characteristic timescale longer than $\sim$ 60 sec, and shows a very soft emission and slower variability. The spectrum of the soft component is characterized by either a broken power law or a black body spectrum. This component might originate from a relatively wider and lower velocity jet or a photosphere of the fireball. By assuming that the soft component is a thermal emission, the radiation radius is initially $4.4 \times 10^{6}$ km, which is a typical radius of a blue supergiant, and its expansion velocity is $2.4 \times 10^{5}$ km/s in the source frame.

description: Social insect colonies routinely face large vertebrate predators, against which they need to mount a collective defense. To do so, honeybees use an alarm pheromone that recruits nearby bees into mass stinging of the perceived threat. This alarm pheromone is carried directly on the stinger, hence its concentration builds up during the course of the attack. Here, we investigate how individual bees react to different alarm pheromone concentrations, and how this evolved response-pattern leads to better coordination at the group level. We first present an individual dose-response curve to the alarm pheromone, obtained experimentally. Second, we apply Projective Simulation to model each bee as an artificial learning agent that relies on the pheromone concentration to decide whether to sting or not. If the emergent collective performance benefits the colony, the individual reactions that led to it are enhanced via reinforcement learning, thus emulating natural selection. Predators are modeled in a realistic way so that the effect of factors such as their resistance, their killing rate or their frequency of attacks can be studied. We are able to reproduce the experimentally measured response-pattern of real bees, and to identify the main selection pressures that shaped it. Finally, we apply the model to a case study: by tuning the parameters to represent the environmental conditions of European or African bees, we can predict the difference in aggressiveness observed between these two subspecies.

Either of vertical or horizontal stripes on clothing makes the wearer look slimmer
Creators: name: Maehara, Goro

name: Wake, Hiromi
Publisher: name: F1000Research
Year: 2015

description: There is a widespread belief that wearing horizontal stripes makes individuals look fatter. Thompson and Mikellidou (2011) showed that the Helmholtz and Oppel-Kundt illusions persist when used on cylinders and pictures of a body, suggesting that the belief is wrong. Swami & Harris (2012), however, reported that the body size was recalled larger when wearing horizontal stripes. We would like to investigate how stripes affect judgements about body size when bodies are being presented in a real space. Observers (n = 197 and 407 for Exp. 1 and 2, respectively) watched mannequins dressed either in horizontal, vertical, or diagonal stripes. We asked observers to rank the order according to perceived slimness. In experiment 1, the mannequin appeared the slimmest for horizontal stripes and looked less slim for diagonal stripes than for other stripes. In experiment 2, where the no-stripe condition was included, the mannequins in striped clothing looked slimmer than the mannequin in uniform grey clothing. The results suggest that any stripes on clothing make the wearer look slimmer. This could be due to that the curves of stripes on a body serve as a cue of depth perception, enhance the perceived depth of a body, and lower the relative body width.

description: The lensing properties of the Plummer model with a central point mass and external shear are derived, including the image multiplicities, critical curves and caustics. This provides a simple model for a flattened galaxy with a central supermassive black hole. For the Plummer model with black hole, the maximum number of images is 4, provided the black hole mass is less than an upper bound which is calculated analytically. This introduces a method to constrain black hole masses by counting images, thus applicable at cosmological distance. With shear, the maximum number of images is 6 and we illustrate the occurrence of an astroid caustic and two metamorphoses.

description: A fundamental difference between a neutron star (NS) and a black hole (BH) is the absence of a physical surface in the latter. For this reason, any remaining kinetic energy of the matter accreting onto a BH is advected inside its event horizon. In the case of an NS, on the contrary, accreting material is decelerated on the NS surface, and its kinetic energy is eventually radiated away. Copious soft photons produced by the NS surface will affect the properties of the Comptonised component dominating spectra of X-ray binaries in the hard state. Thus, parameters of the Comptonised spectra -- the electron temperature $kT_{\rm e}$ and the Compton $y$-parameter, could serve as an important tool for distinguishing BHs from NSs. In this paper, we systematically analyse heretofore the largest sample of spectra from the BH and NS X-ray binaries in the hard state for this purpose, using archival RXTE/PCA and RXTE/HEXTE observations. We find that the BHs and NSs occupy distinctly different regions in the $y-kT_{\rm e}$ plane with NSs being characterised by systematically lower values of $y$-parameter and electron temperature. Due to the shape of the boundary between BHs and NSs on the $y-kT_{\rm e}$ plane, their one-dimensional $y$ and $kT_{\rm e}$ distributions have some overlap. A cleaner one parameter diagnostic of the nature of the compact object in X-ray binaries is provided by the Compton amplification factor $A$, with the boundary between BHs and NSs lying at $A\approx 3.5-4$. This is by far the most significant detection of the imprint of the event horizon on the X-ray spectra for stable stellar-mass BHs.

The effect of prime-target congruence on subsequent prime perception: An ERP study
Creators: name: Sopov, Mikhail
name: Aleshkovskaya, Alisa
Publisher: name: F1000Research
Year: 2015

description: The effect of prior experience on congruent stimuli perception (priming effect) was shown in a wide range of experiments (Henson, 2009). Nevertheless, there is lack of data concerning an impact of stimuli presentation on existing memory traces, related or unrelated to these stimuli. The present study was conducted in order to fill in this gap. Thirty-six subjects participated in the experiment. At the first stage we recorded ERPs in response to visual presentation of word stimuli (targets) with primes, related or unrelated to them (supraliminal associative priming). At the second stage we recorded ERPs in response to repeated primes presentation from each prime-target pair. The second stage results showed that repeated presentation of primes from non-associated word pairs is accompanied by increase of ERPs positivity in 400-500 ms temporal window (N400 component), which is supposedly related to decrease of neural activity (Grill-Spector et al., 2006). We explain obtained results within the predictive coding approach (Friston, 2003). Priming effect can be regarded as a prediction error minimization caused by “imposing” a specific prediction upon a subject through prime presentation. Mismatch between such prediction and sensory input causes rearrangement of memory traces associated with the prediction.

description: Although it is acknowledged that orthographic processing is important, learning the basic association (e.g. binding) between a shape (grapheme) and its sound is critical in the early stages of literacy development.  This study reports an experiment measuring the accuracy with which children could discern between which of two previously heard and seen events (individual items and item strings) were associated with one another. A sample of 87 children (Reception and Year 1) representing low and high ability in literacy skills participated.  The task involved a series of trials in which the child saw and heard two events sequentially (memory stage), with each of the two events consisting of a novel sound(s) and a novel shape(s) presented together. On the same trials, the original binding was maintained, and on different trials, a new binding was formed from one of the event sounds (or string) and one of the event shapes (or string). Not unexpectedly, the results clearly demonstrate that the younger age group of children have substantially more difficulty with the binding task.  Further analyses suggest that the ability to bind is crucial to transitions in the development of writing skills in young children.

description: Gamma Ray Bursts are being searched in many ground based experiments detecting the high energy component (GeV $÷$ TeV energy range) of the photon bursts. In this paper, Fluorescence Detectors are considered as possible candidate devices for these searches. It is shown that the GRB photons induce fluorescence emission of UV photons on a wide range of their spectrum. The induced fluorescence flux is dominated by GRB photons from 0.1 to about 100 MeV and, once the extinction through the atmosphere is taken into account, it is distributed over a wide angular region. This flux can be detected through a monitor of the diffuse photon flux, provided that its maximum value exceeds a threshold value, that is primarily determined by the sky brightness above the detector. The feasibility of this search and the expected rates are discussed on the basis of the current GRB observations and the existing fluorescence detectors.

description: We show that mutual statistics between quantum particles can be tuned to generate emergent novel few particle quantum mechanics for the boundary modes of symmetry-protected topological phases of matter. As a concrete setting, we study a system of pseudofermions, defined as quantum particles with tunable algebra, which lie on two distinct Su-Schrieffer-Heeger (SSH) chains. We find that as the mutual statistics of the particles are tuned -- the boundary modes present in the two chains gets non-trivially entangled showing a sudden jump in their mutual entanglement entropy. We further show that, such tuning of statistics engenders a first-order transition between two topologically non-trivial phases which differ in the behavior of inter-chain entanglement. Using a combination of analytical and numerical techniques and effective modeling, we uncover the rich physics that this system hosts. The results are of particular relevance in context of the study of the effective low energy quantum mechanics of topological edge modes in one hand and their recent realization in ultracold atoms on the other. This then provides for controlled manipulation of such low energy modes.

Such a tendency has important implications for areas of human risk assessment, attention, and the conscious awareness of visual stimuli and allows us to explore how resources are allocated during visual exploration when selective attention is modulated by top-down factors and saliency-driven capture. We investigated brain responses using Event-Related Potentials (ERPs) during detection of increasingly visible targets in individuals that show a high and low propensity to neglect visual stimuli. ERPs components in the latency of N1, N2 and P3 were analysed.

Although the two groups of individuals presented a comparable objective performance on the visual search task, individual with high propensity to detect unexpected stimuli allocated more resources than those who are more likely to visual neglect (Non-IB compared to IB participants in part a and b in figure below). These extra resources may provide an explanation for why such individuals are able to report a concomitant unexpected stimulus, in that they allow both stimuli to gain awareness. Conversely, IB individuals who show propensity to neglect visual stimuli are less likely to detect unexpected stimuli since their early gain is inefficiently used (higher amplification when targets are not detected; see part a top panel) and present a poorer enhancement of targets during the N2pc latency (part b).
Results in our study suggest that low-level visual saliency may play the role of precursor for the awareness of an unexpected change/stimulus in complex scenes.

description: By directly using the probability formulas of quantum trajectories, we construct an auxiliary open quantum system for a periodically driven open quantum system whose dynamics is governed by the Floquet quantum master equation. This auxiliary system can generate a quantum trajectory ensemble that is consistent with the canonical quantum trajectory ensemble. We find that, at a long time limit, though the Lindblad operators are modified, the coherent dynamics of the auxiliary system is the same as that of the original system. A periodically driven two-level quantum system is used to illustrate this construction.

description: In this paper we provide an alternative method to compute correlation functions in the in-in formalism, with a modified set of Feynman rules to compute loop corrections. The diagrammatic expansion is based on an iterative solution of the equation of motion for the quantum operators with only retarded propagators, which makes each diagram intrinsically local (whereas in the standard case locality is the result of several cancellations) and endowed with a straightforward physical interpretation. While the final result is strictly equivalent, as a bonus the formulation presented here also contains less graphs than other diagrammatic approaches to in-in correlation functions. Our method is particularly suitable for applications to cosmology.

description: Superconducting resonators and transmission lines are fundamental building blocks of integrated circuits for millimeter-submillimeter astronomy. Accurate simulation of radiation loss from the circuit is crucial for the design of these circuits because radiation loss increases with frequency, and can thereby deteriorate the system performance. Here we show a stratification for a 2.5-dimensional method-of-moment simulator Sonnet EM that enables accurate simulations of the radiative resonant behavior of submillimeter-wave coplanar resonators and straight coplanar waveguides (CPWs). The Sonnet simulation agrees well with the measurement of the transmission through a coplanar resonant filter at 374.6 GHz. Our Sonnet stratification utilizes artificial lossy layers below the lossless substrate to absorb the radiation, and we use co-calibrated internal ports for de-embedding. With this type of stratification, Sonnet can be used to model superconducting millimeter-submillimeter wave circuits even when radiation loss is a potential concern.

Stability of the Accretion Flows with Stalled Shocks in Core-Collapse Supernovae

description: Bearing in mind the application to the theory of core-collapse supernovae, we performed a global linear analysis on the stability of spherically symmetric accretion flows through a standing shock wave onto a proto neutron star. As unperturbed flows, we adopted the spherically symmetric steady solutions to the Euler equations obtained with realistic equation of state and formulae for neutrino reaction rates taken into account. Then we solved the equations for linear perturbations numerically, and obtained the eigen frequencies and eigen functions. We found (1) the flows are stable for all modes if the neutrino luminosity is lower than $\sim 1\times 10^{52}$ ergs/s for $\dot{M}=1.0M_{\odot}/{\rm s}$. (2) For larger luminosities, the non-radial instabilities are induced, probably via the advection-acoustic cycles. Interestingly, the modes with $\ell=2$ and 3 become unstable at first for relatively low neutrino luminosities, e.g. $\gtrsim 2-3\times 10^{52}$ ergs/s for the same accretion rate, whereas the $\ell=1$ mode is the most unstable for higher luminosities, $\sim 3-7\times 10^{52}$ ergs/s. These are all oscillatory modes. (3) For still larger luminosities, $\sim 7\times 10^{52}$ ergs/s for $\dot{M}=1.0M_{\odot}/{\rm s}$, non-oscillatory modes, both radial and non-radial, become unstable. These non-radial modes were identified as convection. We confirmed the results obtained by numerical simulations that the instabilities induced by the advection-acoustic cycles are more important than the convection for lower neutrino luminosities.

A New Action for Cosmology

description: We present a new action which reproduces the cosmological sector of general relativity in both the Friedmann-Lemaitre-Robertson-Walker (FLRW) and Bianchi models. This action makes no reference to the scale factor, and is of a frictional type first examined by Herglotz. We demonstrate that the extremization of this action reproduces the usual dynamics of physical observables, and the symplectification of this action is the Einstein-Hilbert action for cosmological models. We end by discussing some of the increased explanatory power produced by considering the reduced physical ontology resulting from eliminating scale.

A sharp rise in the detection rate of broad absorption line variations in a quasar SDSS J141955.26+522741.1

description: We present an analysis of the variability of broad absorption lines (BALs) in a quasar SDSS J141955.26+522741.1 at $z=2.145$ with 72 observations from the Sloan Digital Sky Survey Data Release 16 (SDSS DR16). The strong correlation between the equivalent widths of BAL and the continuum luminosity, reveals that the variation of BAL trough is dominated by the photoionization. The photoionization model predicts that when the time interval $ΔT$ between two observations is longer than the recombination timescale $t_{\rm rec}$, the BAL variations can be detected. This can be characterized as a "sharp rise" in the detection rate of BAL variation at $ΔT=t_{\rm rec}$. For the first time, we detect such a "sharp rise" signature in the detection rate of BAL variations. As a result, we propose that the $t_{\rm rec}$ can be obtained from the "sharp rise" of the detection rate of BAL variation. It is worth mentioning that the BAL variations are detected at the time-intervals less than the $t_{\rm rec}$ for half an order of magnitude in two individual troughs. This result indicates that there may be multiple components with different $t_{\rm rec}$ but the same velocity in an individual trough.

Analytic results for scalar-mediated Higgs boson production in association with two jets

description: We present compact analytic formulae for all one-loop amplitudes representing the production of a Higgs boson in association with two jets, mediated by a colour triplet scalar particle. Many of the integral coefficients present for scalar mediators are identical to the case when a massive fermion circulates in the loop, reflecting a close relationship between the two theories. The calculation is used to study Higgs boson production in association with two jets in a simplified supersymmetry (SUSY) scenario in which the dominant additional contributions arise from loops of top squarks. The results presented here facilitate an indirect search for top squarks in this channel, by a precision measurement of the corresponding cross-section. However, we find that the potential for improved discrimination between the SM and SUSY cases suggested by the pattern of results in the 1- and 2-jet samples is unlikely to be realized due to the loss in statistical power compared to an inclusive analysis.
