description: Objectives: Loneliness has a long-established link with depression; however, patterns of loneliness, specifically transient (short-term) and chronic loneliness (longer-term), have seldom been researched in terms of their associations with depression and psychiatric distress. We investigated whether chronic loneliness could predict higher levels of psychiatric distress and higher chance of depression diagnosis (via self-report) than transient and no loneliness. Methods: We used data from 18,999 participants in Waves 9 and 10 of the Understanding Society survey: a nationally representative study of adults in the United Kingdom. The study used a between-subjects, cross-sectional, design, where participants' scores on loneliness measures across two time points were combined to form patterns of loneliness, and participants were compared on their levels of psychiatric distress and depression diagnoses across the three loneliness groups: chronic loneliness (lonely at both time points), transient loneliness (lonely at one time point) and no loneliness. Results: Regression analyses revealed that patterns of lone?liness predicted both the likelihood of participants reporting a history of depression diagnosis and participants' levels of psychiatric distress. The chronic loneliness group had the highest likelihood of self-reported depression diagnosis and had the highest levels of psychiatric distress, compared to both the transient and no loneliness groups. Transient loneliness, in turn, predicted higher likelihood of reporting a history of depression diagnosis and higher levels of psychiatric distress than the no loneliness group. Conclusions: The study replicates and extends prior findings, suggesting that prolonged loneliness even over the course of one year is a risk factor for poorer mental health.

HITRAN

description: We evaluated the improvements in successive versions (1996 - 2004) of HITRAN (1) and other molecular line parameter data set (2) to correctly simulate infrared (IR) and near-infrared (NIR) CO 2 transmittance spectra. Understanding the global sources and sinks of CO 2 requires highly accurate measurements (ó 0.3%) and makes extreme de- mands on the spectroscopy. We evaluated the line parameter data sets by fitting solar absorption spectra measured by the JPL MkIV FTIR spectrometer (3) and the Caltech FT spectrometer (4). The JPL spectra cover the entire 650 - 5650 cm-1 spectral region simultaneously and were measured during recent balloon ìights under conditions that were closely monitored by in situ sensors(5). The Caltech spectra, measured during sum- mer 2004 from Park Falls, WI, cover the entire 4,000 - 11,000 cm-1 spectral region simultaneously. The measurements were made under conditions that were also closely monitored by in situ sensors (continuous CO 2 monitors, weekly ìask sampling and air- craft profiles).(6)

This work benefits the HITRAN user community by documenting and highlighting inadequacies in the data set and quantifying their likely e’ect on retrieved CO 2 col- umn. The consistency between retrieved column-averaged mole fraction of CO 2 ( XCO 2 ) and measured surface CO 2 is an important demonstration of the adequacy of the spec- troscopy.  The work provides an objective basis for assessing the adequacy and self- consistency of the existing HITRAN data set and for quantifying the improvements (or otherwise) produced by new CO 2 line parameters. It also helps to prioritize needs for additional laboratory studies.(7)

A Framework for Generalising the Newton Method and Other Iterative Methods from Euclidean Space to Manifolds

Year: 2012

description: The Newton iteration is a popular method for minimising a cost function on Euclidean space. Various generalisations to cost functions defined on manifolds appear in the literature. In each case, the convergence rate of the generalised Newton iteration needed establishing from first principles. The present paper presents a framework for generalising iterative methods from Euclidean space to manifolds that ensures local convergence rates are preserved. It applies to any (memoryless) iterative method computing a coordinate independent property of a function (such as a zero or a local minimum). All possible Newton methods on manifolds are believed to come under this framework. Changes of coordinates, and not any Riemannian structure, are shown to play a natural role in lifting the Newton method to a manifold. The framework also gives new insight into the design of Newton methods in general.

description: Planetary scientists seek to determine the compositions, dynamics, energetics, and chemical behaviors of planetary atmospheres through measurements of atmospheric absorption or emission in a number of wavelength regions. Laboratory studies of molecular spectra are often required to properly interpret telescope and spacecraft observations, particularly for atmospheres of planets such as Mars and Venus that have compositions and temperature and pressure regimes quite di’erent from those in the Earth's atmosphere. While many of the necessary spectroscopic parameters are already available in databases such as HITRAN, updates are needed to meet the changing requirements of terrestrial planetary remote sensing missions. Key issues include (1) expanding line lists to cover near-infrared transitions, (2) adding parameters for isotopologues, (3) lower intensity cuto’s to allow more weak transitions to be listed, and (4) adding parameters for broadening and shifts by gases other than air. Specific requirements, discussed in the recent Chapman Conference on Exploring Venus as a Terrestrial Planet and at the NASA Astrobiology Science Conference, will be reviewed

description: The types of THz absorption studies will be discussed. These include i) measurements of the water-vapor continuum from 12 ° 55 cm ° 1 (0 : 4 ° 1 : 83 THz) using a multipass cell coupled to a FIR Fourier transform spectrometer and ii) high resolution THz laser studies of the self-broadened rotational lines of water over a temperature range from 263 ° 340 K and a pressure range from 30-1400 Pa. For the continuum studies, measurements were made at a room temperature and with water vapor and nitrogen pressures up to 2.2 kPa and 81 kPa, respectively. The eÆects of the choice of lineshape function and far-wing cut-oÆ factors on the continuum absorption will be discussed. For the high resolution THz studies, the FWHM widths of pure Lorentzian lines were found to vary between 0 : 67 ° 1 : 07 cm ° 1 atm ° 1 and depend on the J , K a and K c quantum numbers as well as temperature. The observed pressure induced shifts, ±∫ (P) ; ranged from 0 : 013 ° 0 : 046 cm ° 1 atm ° 1 . The measured linewidths exhibit the (T 0 /T) n power law dependence on temperature. The best Øt exponent n varied from 0.56 to 0.81 relative to other lines in the set. A decrease in ±∫ (T) with increasing temperature was found to vary between (2-5) £ 10 ° 3 cm ° 1 atm ° 1 over the 300 ° 340 K temperature range. New developments in instrumentation will be discussed with emphasis on coupling the high-resolution THz photomixer source to the long path White cell for proposed measurements on O 2 .

description: We consider superconformal and supersymmetric field theories on four-dimensional Lorentzian curved space-times, and their five-dimensional holographic duals. As in the Euclidean signature case, preserved supersymmetry for a superconformal theory is equivalent to the existence of a charged conformal Killing spinor. Differently from the Euclidean case, we show that the existence of such spinors is equivalent to the existence of a null conformal Killing vector. For a supersymmetric field theory with an R-symmetry, this vector field is further restricted to be Killing. We demonstrate how these results agree with the existing classification of supersymmetric solutions of minimal gauged supergravity in five dimensions.

description: Laboratory absorption spectra of H2O-D2O mixtures have been recorded in the spectral region 8800-1500 cm-1 by Fourier transform spectroscopy at high resolution (0.03 cm-1 ). The 50 m base long cell from Reims was used to record spectra with total pressure £ absorption path products of about 6000 torr m. In the continuation of our previous work concerning water vapor 1 ; 2 ; 3 ; 4 ; 5 ; 6 ; 7 ; 8 ; 9 ; 10 , the present study deals with the Deuterium enriched spectra. Two spectra with diÆerent mixing ratios for H 2 O, HDO and D 2 O species were recorded. The identiØcation of the HDO and D 2 O lines has been made by comparison of ratios between pure and enriched spectra. Partial pressures were carefully determined using (i) H2 ^16O previously determined line intensities, (ii) HDO and D 2 O line intensity ratios, and (iii) total pressures. The lines identiØcation was checked through the evolution of the integrated absorption coe±cients with the partial pressures. The observed lines have been Øtted to Voigt line proØles from which line positions (cali- brated afterwards), integrated absorption cross-sections and self-broadening coe±cients have been determined. For the two deuterated species the integrated absorption cross sections could be measured down to 5 10-27 cm/molecule. Comparisons with the most recent experimental data and calculations are presented.

Implications of nonlinearity for spherically symmetric accretion

Year: 2012
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We subject the steady solutions of a spherically symmetric accretion flow to a time-dependent radial perturbation. The equation of the perturbation includes nonlinearity up to any arbitrary order, and bears a form that is very similar to the metric equation of an analogue acoustic black hole. Casting the perturbation as a standing wave on subsonic solutions, and maintaining nonlinearity in it up to the second order, we get the time-dependence of the perturbation in the form of a Liénard system. A dynamical systems analysis of the Liénard system reveals a saddle point in real time, with the implication that instabilities will develop in the accreting system when the perturbation is extended into the nonlinear regime. The instability of initial subsonic states also adversely affects the temporal evolution of the flow towards a final and stable transonic state.

description: A rational pseudo-rotation $f$ of the torus is a homeomorphism homotopic to the identity with a rotation set consisting of a single vector $v$ of rational coordinates. We give a classification for rational pseudo-rotations with an invariant measure of full support, in terms of the deviations from the constant rotation $x\mapsto x+v$ in the universal covering. For the simpler case that $v=(0,0)$, it states that either every orbit by the lifted dynamics is bounded, or the displacement in some rational direction is uniformly bounded (implying that the dynamics is annular) or the set of fixed points of $f$ contains a large continuum which is the complement of a disjoint union of disks (i.e. a fully essential continuum). In the analytic setting, the latter case is ruled out. In order to prove this classification, we introduce tools that are of independent interest and can be applied in a more general setting: in particular, a geometric result about the quasi-convexity and existence of asymptotic directions for certain chains of disks, and a Poincaré recurrence theorem on the universal covering for irrotational measures.

description: Τα τελευταία χρόνια η συνεχόμενη αύξηση της εξάρτησης των ανθρώπων γύρω από τις ηλεκτρονικές συσκευές έχει οδηγήσει στην εμφάνιση ολοένα και περισσότερο απαιτητικών εφαρμογών, οι οποίες χρειάζονται όλο και περισσότερους υπολογιστικούς πόρους αλλά και την εύκολη δυνατότητα επεκτασιμότητας και λειτουργίας τους σε μεγάλη κλίμακα. Το πρόβλημα αυτό λοιπόν προσπαθήσει να επιλύσει η αρχιτεκτονική των microservices. O όρος microservices αναφέρθηκε πρώτη φορά σε ένα συνέδριο από τον Dr. Peter Rodgers το 2005 και παρουσιάστηκε με τον όρο «Micro-Web-Services». Σκοπός της συγκεκριμένης αρχιτεκτονικής ήταν η διάσπαση μεμονωμένων μεγάλων μονολιθικών εφαρμογών σε πολλαπλά ανεξάρτητα μικροσυστήματα, καθιστώντας έτσι τον κώδικα πιο απλό , εύκολα διαχειρίσιμο και επεκτάσιμο. Στην παρούσα διπλωματική εργασία λοιπόν θα εξετάσουμε την ανάπτυξη και την υλοποίηση ενός back-end συστήματος με την χρήση microservices, το συγκεκριμένο σύστημα θα αναπτυχθεί πάνω στο τομέα της Υγείας (Ιατρικός Φάκελος) ο οποίος αποτελεί ένα πολύ εύστοχο και σύνθετο σενάριο εφαρμογής ως προς την μοντελοποίηση του σε πολλαπλά microservices. Το συγκεκριμένο σύστημα θα ονομάζεται Medbook και θα αποτελείται από πέντε αυτόνομα και ανεξάρτητα microservices, όπου το καθένα θα εξυπηρετεί ένα συγκεκριμένο και μοναδικό σκοπό σε επίπεδο business logic και θα επικοινωνούν μεταξύ τους . Τα microservices αυτά έχουν τις εξής ονομασίες: User, Personel, PatientDemographics, Lis (Laboratory Information System) και ClinicalInformation. Πιο συγκεκριμένα μέσω των συγκεκριμένων microservices θα μπορεί να γίνει η δημιουργία και η διαχείριση ενός Ιατρικού Φακέλου για έναν ασθενή, ο οποίος θα περιέχει όλα τις απαραίτητες λειτουργικότητες για να χρησιμοποιηθεί από ένα η πολλαπλά νοσοκομεία όπως ιστορικό, επισκέψεις σε εξωτερικά η εσωτερικά ιατρεία νοσοκομείων, διεξαγωγή εξετάσεων, καταγραφή αποτελεσμάτων και χορήγηση φαρμάκων.

description: UGC 4483 is a nearby Blue Compact Dwarf (BCD) galaxy. HST observations have resolved the galaxy into single stars and this has led to the derivation of its star formation history and to a direct estimate of its stellar mass. We have analysed archival VLA observations of the 21 cm line and found that UGC 4483 has a steeply-rising rotation curve which flattens in the outer parts at a velocity of ~20 km/s. Radial motions of ~5 km/s may also be present. As far as we know, UGC 4483 is the lowest-mass galaxy with a differentially rotating HI disk. The steep rise of the rotation curve indicates that there is a strong central concentration of mass. We have built mass models using the HST information on the stellar mass to break the disk-halo degeneracy: old stars contribute ~50$%$ of the observed rotation velocity at 2.2 disk scale-lengths. Baryons (gas and stars) constitute an important fraction of the total dynamical mass. These are striking differences with respect to typical dwarf irregular galaxies (dIrrs), which usually have slowly-rising rotation curves and are thought to be entirely dominated by dark matter. BCDs appear to be different from non-starbursting dIrrs in terms of their HI and stellar distributions and their internal dynamics. To their high central surface brightnesses and high central HI densities correspond strong central rotation-velocity gradients. This implies that the starburst is closely related with the gravitational potential and the concentration of gas. We discuss the implications of our results on the properties of the progenitors/descendants of BCDs.

Type 2 Diabetes Mellitus

description: Recent data have suggested a strong possible link between Type 2 Diabetes Mellitus and Alzheimer's disease (AD), although exact mechanisms linking the two are still a matter of research and debate. Interestingly, both are diseases with high incidence and prevalence in later years of life. The link appears so strong that some scientists use Alzheimer's and Type 3 Diabetes interchangeably. In depth study of recent data suggests that the anti diabetic drugs not only have possible role in treatment of Alzheimer's but may also arrest the declining cognitive functions associated with it. The present review gives an insight into the possible links, existing therapeutics and clinical trials of anti diabetic drugs in patients suffering from AD primarily or as co-morbidity. It may be concluded that the possible beneficial effects and usefulness of the current anti diabetic drugs in AD cannot be neglected and further research is required to achieve positive results. Currently, several drug trials are in progress to give conclusive evidence based data.

description: We derive an analytic expression for the shear viscosity of an ultra-relativistic gas in presence of both elastic $2\to 2$ and inelastic $2\leftrightarrow 3$ processes with isotropic differential cross sections. The derivation is based on the entropy principle and Grad's approximation for the off-equilibrium distribution function. The obtained formula relates the shear viscosity coefficient $η$ to the total cross sections $σ_{22}$ and $σ_{23}$ of the elastic resp. inelastic processes. The values of shear viscosity extracted using the Green-Kubo formula from kinetic transport calculations are shown to be in excellent agreement with the analytic results which demonstrates the validity of the derived formula.

description: The Archaean Kalgoorlie Terrane, within the Eastern Goldfields Province of the Yilgarn Craton, Western Australia, preserves a succession dominated by mafic/ultramafic rocks at it's base, overlain by the felsic volcaniclastic and sedimentary succession of the Black Flag Beds (BFB's). The BFB's are composed overwhelmingly of dacitic-andesitic volcaniclastic rocks, with lava facies poorly preserved. The Sedimentary facies range from mudrock to boulder sized conglomerates and breccias. Throughout all sedimentary successions of the BFB's, the background sedimentation was tranquil water mudrock deposition, indicating a below wave base depositional environment. The volcaniclastic facies have been deposited by turbidity currents, density modified grain flows and hemipelagic sedimentation processes. Facies analysis indicates that the dominant depositional systems that developed during the period of BFB sedimentation were submarine fan and slope apron systems. Five defined facies assemblages represent proximal to distal depositional settings within the subaqueous basins. Progradational, retrogradational and aggradational trends of submarine fan systems are sommon and are defined by vertically stacked facies assemblages. [...]

description: The standard extremal p-brane solutions in supergravity are known to allow for a generalisation which consists of adding a linear dependence on the world-volume coordinates to the usual harmonic function. In this note we demonstrate that remarkably this generalisation goes through in exactly the same way for p-branes with fluxes added to it that correspond to fractional p-branes. We relate this to warped orientifold compactifications by trading the Dp-branes for Op-planes that solve the RR tadpole condition. This allows us to interpret the worldvolume dependence as due to lower-dimensional scalars that flow along the massless directions in the no-scale potential. Depending on the details of the fluxes these flows can be supersymmetric domain wall flows. Our solutions provide explicit examples of backreacted orientifold planes in compactifications with non-constant moduli.

description: The Ihara limit (or -constant) $A(q)$ has been a central problem of study in the asymptotic theory of global function fields (or equivalently, algebraic curves over finite fields). It addresses global function fields with many rational points and, so far, most applications of this theory do not require additional properties. Motivated by recent applications, we require global function fields with the additional property that their zero class divisor groups contain at most a small number of $d$-torsion points. We capture this by the torsion limit, a new asymptotic quantity for global function fields. It seems that it is even harder to determine values of this new quantity than the Ihara constant. Nevertheless, some non-trivial lower- and upper bounds are derived. Apart from this new asymptotic quantity and bounds on it, we also introduce Riemann-Roch systems of equations. It turns out that this type of equation system plays an important role in the study of several other problems in areas such as coding theory, arithmetic secret sharing and multiplication complexity of finite fields etc. Finally, we show how our new asymptotic quantity, our bounds on it and Riemann-Roch systems can be used to improve results in these areas.

description: We use high resolution cosmological simulations of Milky Way-mass galaxies that include both baryons and dark matter to show that baryonic physics (energetic feedback from supernovae and subsequent tidal stripping) significantly reduces the dark matter mass in the central regions of luminous satellite galaxies. The reduced central masses of the simulated satellites reproduce the observed internal dynamics of Milky Way and M31 satellites as a function of luminosity. We use these realistic satellites to update predictions for the observed velocity and luminosity functions of satellites around Milky Way-mass galaxies when baryonic effects are accounted for. We also predict that field dwarf galaxies in the same luminosity range as the Milky Way classical satellites should not exhibit velocities as low as the satellites, since the field dwarfs do not experience tidal stripping. Additionally, the early formation times of the satellites compared to field galaxies at the same luminosity may be apparent in the star formation histories of the two populations. Including baryonic physics in Cold Dark Matter models naturally explains the observed low dark matter densities in the Milky Way's dwarf spheroidal population. Our simulations therefore resolve the tension between kinematics predicted in Cold Dark Matter theory and observations of satellites, without invoking alternative forms of dark matter.

description: We use current measurements of the expansion rate $H(z)$ and cosmic background radiation bounds on the spatial curvature of the Universe to impose cosmological model-independent constraints on cosmic opacity. To perform our analyses, we compare opacity-free distance modulus from $H(z)$ data with those from two supernovae Ia compilations: the Union2.1 plus the most distant spectroscopically confirmed SNe Ia (SNe Ia SCP-0401 $z=1.713$) and two Sloan Digital Sky Survey (SDSS) subsamples. The influence of different SNe Ia light-curve fitters (SALT2 and MLCS2K2) on the results is also verified. We find that a completely transparent universe is in agreement with the largest sample in our analysis (Union 2.1 plus SNe Ia SCP-0401). For SDSS sample a such universe it is compatible at $< 1.5σ$ level regardless the SNe Ia light-curve fitting used.

description: High Demand for Integration of Skills in ELT lessons: Paving the way for better Communication at Workplaces By Firos Kalarikkal (Lecturer, English language Centre, University of Technology and Applied Sciences-Ibra) Language acquisition has been considered as the primary ingredient for successful communication in every civil society. Meanwhile, communication has become the cardinal value point in modern civil and business community. Thus, learning a language with an aim of communicative competency gained much attention and facet of the language learning has been revitalized accordingly. This is very evident in the case of English language teaching and learning. The curriculum framework more tends to inculcate more internalization of the language skills to produce better proficiency of the learners in the language. As far as the job market is concerned, it can only accommodate and retain the candidates who has mastery of the work-related language. And the lion share of the job positions, English language is the main medium of business deal. Therefore, English language teaching community needs to bring proper blend of skills in the learning activities for their learners in each lesson. As the new motto emerged, ‘English for life’, the learners should be equipped with the ample exposure to the real-life situations in every lesson they get. Enabling students to have discourse at different social and job contexts needs to be the focal point. The lesson proceedings should reflect an integrated skill approach rather that segregated method. This presentation aims to propagate the varied ways such as TBL and CBL which with educators can bring successful integration of skill to prepare their learners to meet the communication challenges of the techno era. The presentation will also shed light to the challenges that teachers may face in this and recommend some suggestions. Key words: Language Acquisition, TBL, CBL,

description: We focus on the generating series for the rational special values of Pellarin's $L$-series in $1 \leq s \leq 2(q-1)$ indeterminates, and using interpolation polynomials we prove a closed form formula relating this generating series to the Carlitz exponential, the Anderson-Thakur function, and the Anderson generating functions for the Carlitz module. We draw several corollaries, including explicit formulae and recursive relations for Pellarin's $L$-series in the same range of $s$, and divisibility results on the numerators of the Bernoulli-Carlitz numbers by monic irreducibles of degrees one and two.

description: Immer mehr Wissenschaftlerinnen und Wissenschaftler möchten ihre Werke open access verfügbar machen. Der Gesetzgeber hat das durch die Reform des Paragrafen 38 des Urheberrechtsgesetzes für einen Teil von ihnen erleichtert. Viele sind jedoch von der Gesetzesänderung nicht betroffen, weil sie nicht in Periodika veröffentlichen – vor allem Autorinnen und Autoren in den Geistes- und Gesellschaftswissenschaften –, oder sie möchten Werke veröffentlichen, die vor der Neuregelung des Gesetzes entstanden sind. Das vorliegende Policy Pa- per bietet ihnen zum einen einen Überblick über die geltende Rechtslage, zum anderen eine Entscheidungshilfe dabei herauszufinden, in welcher rechtlichen Situation sie sich gegenüber ihrem Verlag befinden. Schließlich werden konkrete Formulierungsvorschläge für Vertragszusätze auf ihre Wirksamkeit hin untersucht. Wissenschaftsorganisationen sollten versuchen, die zahlreichen vorliegenden Formulierungen rechtssicher zu vereinheitlichen und sie der Wissenschaftsge- meinde besser bekannt zu machen.

description: We prove the formula for the complete tree-level $S$-matrix of $\mathcal{N}=8$ supergravity recently conjectured by two of the authors. The proof proceeds by showing that the new formula satisfies the same BCFW recursion relations that physical amplitudes are known to satisfy, with the same initial conditions. As part of the proof, the behavior of the new formula under large BCFW deformations is studied. An unexpected bonus of the analysis is a very straightforward proof of the enigmatic $1/z^2$ behavior of gravity. In addition, we provide a description of gravity amplitudes as a multidimensional contour integral over a Grassmannian. The Grassmannian formulation has a very simple structure; in the N$^{k-2}$MHV sector the integrand is essentially the product of that of an MHV and an $\overline{\rm MHV}$ amplitude, with $k+1$ and $n-k-1$ particles respectively.

description: Methyl bromine is of interest for atmospheric applications, since this molecule is directly involved in the catalytic destruction of ozone in the lower stratosphere. At the present time no spectroscopic data is available in the atmospheric databases as HITRAN or GEISA.
Using FT spectra (Bruker IFS 120, unapodized FWHM resolution of 0.001 cm ^-1 ) of methyl bromide CH 3 Br, absolute line positions and intensities, as well as self-and N 2 - broadening coe±cients have been measured for about 1200 lines between 880 and 1050 cm ^-1 in the v6 band of ^12CH3 ^79Br and 12^CH3 81^Br. These measurements improve the accuracy on wavenumbers and line intensities previously obtained and lead to a complete set of self- and N 2 -broadening coe±cients for which clear J -and K -dependences have been observed for the first time. A multispectrum fitting procedure has been used to retrieve simultaneously the line parameters from 6 experimental spectra recorded at different pressures of CH 3 Br and N 2 . A wavenumber calibration has been performed using the line frequencies of the v2 band of NH 3 . Average absolute accuracies of the measurements have been estimated around 0.0005 cm ^-1 for line positions, 5% for line intensities, and 5-10% for broadening coe±cients. A theoretical treatment of wavenumbers permitted the prediction of assignments and wavenumbers for the whole 10- π m spectral region. Line intensities have been analyzed to deduce the eÆective vibrational transition moment squared as well as Herman-Wallis coe±cients. Self-and N 2 -broadening coe±cients have been reduced using an empirical polynomial expansion function of J and K .
A complete line list containing line positions, intensities, self- and N 2 -broadening coe±cients has then been generated for atmospheric purposes with all lines from 820 to 1120 cm ^-1 having intensities greater than 10 ^-5 cm ^-2 ¢ atm ^-1 .

Isospin-Violating Dark Matter at the LHC

description: We consider a toy model of dark matter (DM) with a gauge singlet Dirac fermion that has contact interactions to quarks that differ for right-handed up and down quarks. This is motivated by the isospin-violating dark matter scenario that was proposed to reconcile reported hints of direct DM detection with bounds from non-observation of the signal in other experiments. We discuss how the effects of isospin violation in these couplings can be observed at the LHC. By studying events with large missing transverse momentum, we show that the ratio of mono-photon and mono-jet events is sensitive to the ratio of the absolute values of the couplings to the up and down quarks, while a dedicated study of di-jet plus missing transverse momentum events can reveal their relative sign. We also consider how our results are modified if instead of a contact interaction, a particle that mediates the interaction is introduced. Our methods have broad applicability to new physics that involves unequal couplings to up and down quarks.
