Substance use and sexually transmitted infections, barriers to sexual health care and the role of enhanced outreach services on STI trends among an inner-city population in Vancouver, Canada
Creators: name: Rusch, Melanie Lena Anne
Publisher: name: University of British Columbia
Year: 2010

description: In high risk communities such as Vancouver’s Downtown Eastside (DTES), persistently high rates of sexually transmitted infections (STIs) warrants further research. This thesis examines prevalence of STIs from two perspectives: (1) factors associated with increased STIs, and (2) factors influencing access to treatment. The Community Health And Safety Evaluation (CHASE) afforded a population sample in which to examine drug use patterns associated with STIs, STI trends and program influences. An extension of CHASE, the Women’s Night (WN) survey, enabled further examination of program impact, assessing STI screening in this setting. Factors influencing access of sexual health care were assessed among the WN population, focusing on a novel STI-related stigma scale. Examining drug use patterns and STIs revealed that, among HIV-negative women, crack cocaine use was independently associated with STIs (AOR: 2.6, 95% CI: 1.1-6.5), while among HIV-positive women, episodic drug use remained independently associated with STIs (AOR: 5.8, 95% CI: 1.4-23.5). Interaction between drugs was not seen, although estimated odds for dual-users of crack and crystal methamphetamine was additive, suggesting specific risks associated with drug type. CHASE and regional STI trends were similar, although for gonorrhoea and syphilis CHASE prevalences were ten times higher. A recent syphilis outbreak was evident in both the CHASE and regional data. Shifted peaks in the CHASE cohort may reflect the influence of enhanced partner tracing and peer-based networking strategies. The WN program had a low cross-sectional prevalence of chlamydia (2%) despite active sex work and high drug use. Nearly 75% of the WN population reported a pap smear, and approximately 50% reporting STI testing in the past year. Accessing pap smears was influenced positively by education (OR: 4.5, 95% CI: 1.1-18.0) and negatively by injection drug use (OR: 0.25, 95% CI: 0.08-0.86). STI-stigma was not associated with accessing pap smears; however, internal stigma was associated with STI testing (OR: 0.43; 95% CI: 0.20-0.91). Developing strategies for engaging hard-to-reach populations, developing less stigmatizing messages of prevention, and breaking down barriers that prevent regular sexual health care among women are important and necessary steps in reducing the impact of STIs.

description: In the emerging world of twisted bilayer structures, the possible configurations are limitless, which enables for a rich landscape of electronic properties. In this paper, we focus on twisted bilayer transition metal dichalcogenides (TMDCs) and study its properties by means of an accurate tight-binding model. We build structures with different angles and find that the so-called flatbands emerge when the twist angle is sufficiently small (around 7.3$^{\circ}$). Interestingly, the band gap can be tuned up to a 2.2\% (51 meV) when the twist angle in the relaxed sample varies from 21.8$^{\circ}$ to 0.8$^{\circ}$. Furthermore, when looking at local density of states we find that the band gap varies locally along the moirè pattern due to the change in the coupling between layers at different sites. Finally, we also find that the system can suffer a transition from a semiconductor to a metal when a sufficiently strong electric field is applied. Our study can serve as a guide for the practical engineering of the TMDCs based optoelectronic devices.

description: A Koreai Köztársaság (Dél-Korea) a kelet-ázsiai régió egyik legjelentősebb gazdasága, amely mára többé-kevésbé eredményesen kilábalt az 1997-98. évi gazdasági- pénzügyi válságból. Az ország külgazdasági stratégiájában, jóllehet ma is meghatározó szerepe van két legfontosabb partnerének, az Egyesült Államoknak és Japánnak, ugyanakkor fokozatosan bővíti kapcsolatait egyrészt saját térsége más államaival (Kína, ASEAN), másrészt a tőle távolabb eső fejlett, illetve felzárkózóban lévő európai országokkal. A Koreai Köztársaság és Magyarország gazdasági (kereskedelmi és működőtőke-beruházási) kapcsolatai szintén bővülnek. Az írás a Koreai Köztársaság gazdasága jelenlegi helyzetének néhány sajátosságát, az EU és a Koreai Köztársaság külgazdasági kapcsolatainak alakulását mutatja be, továbbá rövid ismertetést ad a KNDK (Észak-Korea) és az EU közötti gazdasági kapcsolatokról is. -------------- The Republic of Korea (South Korea) constitutes one of the most important economies of the Far Eastern region. By now it has more or less efficiently recovered from the 1997/98 economic and financial crisis. The United States and Japan, the two most important export & import partners of the country, still play a decisive role. At the same time, however, South Korea also continually increases its connections with other countries of its region (China, ASEAN countries), on the one hand, and the closing-up countries of Europe, on the other hand. Thus, the economic relations of the Republic of Korea to Hungary (trade and operating capital investment) are increasing as well. The paper contains the description of some specific features of the present economic situation of the Republic of Korea, and the formation of the export & import relations between the European Union and the Republic of Korea. There is also a brief description of the economic relations between the people’s Democratic Republic of Korea (North Korea) and the European Union.

description: Glueballs and hybrids are predicted to exist but searches for them have failed to provide conclusive evidence. One--gluon exchange is not an important part of strong interactions in this energy regime. Instead, quarks seem to interact indirectly, via changes of the QCD vacuum. Strong interactions seem to be governed by instanton--induced interactions; the chiral soliton model gives a more suitable interpretation of the $Θ^+(1540)$ than models based on the dynamics of four quarks and one antiquark.

description: Edward John Hammond enlisted in the Norfolk Yeomanry on 16 Feb 1916 as Private 2905. Sometime in 1917 he was transferred to G/26047 8th Battalion East Surrey Regiment. Edward fought with the East Surreys, through 1917. In March 1918 the East Surrey Regt were in the front line, at the start of Operation Michael and the 'Kaiserslacht'. Between 1-3 April 1918 they relieved Australian battalions on a line near Villers-Bretonneux. A report from Private J Cordery 5392 described the action in which Edward died.The Report states:"Early in April at Villers-Bretonneux, I saw him fall close to me in the open, hit in the back and leg by bullets. We were retreating and his body was left. I knew him well, he came from Norfolk."Edward was listed in the War Diary as wounded but was actually missing. His body was later recovered and buried by Canadian Forces. Edward id buried at Crucifix Corner Cemetery Plot C IX 2.Edward was the second son of Frederick and Lucy Louisa Hammond and was born 1 Feb 1897 at Runhall, he was one of seven children. At the time of enlistment Edward was living at 4 Letton Road, Shipdham.

description: We described the design and operation principles of a new tunable-filter photometer developed for the 1-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences and the 2.5-m telescope of the Sternberg Astronomical Institute of the Moscow State University. The instrument is mounted on the scanning Fabry-Perot interferometer operating in the tunable-filter mode in the spectral range of 460-800 nm with a typical spectral resolution of about 1.3 nm. It allows one to create images of galactic and extragalactic nebulae in the emission lines having different excitation conditions and to carry out diagnostics of the gas ionization state. The main steps of observations, data calibration, and reduction are illustrated by examples of different emission-line objects: galactic HII regions, planetary nebulae, active galaxies with extended filaments, starburst galaxies, and Perseus galaxy cluster.

description: We present the results of a near-infrared monitoring program of the Anomalous X-ray Pulsar 1E 2259+586, performed at the Gemini Observatory. This program began three days after the pulsar's 2002 June outburst, and spans ~1.5 years. We find that after an initial increase associated with the outburst, the near-infrared flux decreased continually and reached the pre-burst quiescent level after about one year. We compare both the near-infrared flux enhancement and its decay to those of the X-ray afterglow, and find them to be remarkably consistent. Fitting simple power laws to the RXTE pulsed flux and near-infrared data for t>1 day post-burst, we find the following decay indices: alpha=-0.21+/-0.01 (X-ray), alpha=-0.21+/-0.02 (near-infrared), where flux is a function of time such that F is proportional to t^alpha. This suggests that the enhanced infrared and X-ray fluxes have a physical link post-outburst, most likely from the neutron-star magnetosphere.

description: We report the first discovery of a thick-disk planet, LHS 1815b (TOI-704b, TIC 260004324), detected in the TESS survey. LHS 1815b transits a bright (V = 12.19 mag, K = 7.99 mag) and quiet M dwarf located $ 29.87\pm0.02 pc$ away with a mass of $0.502\pm0.015 M_{\odot}$ and a radius of $0.501\pm0.030 R_{\odot}$. We validate the planet by combining space and ground-based photometry, spectroscopy, and imaging. The planet has a radius of $1.088\pm 0.064 R_{\oplus}$ with a $3 σ$ mass upper-limit of $8.7 M_{\oplus}$. We analyze the galactic kinematics and orbit of the host star LHS1815 and find that it has a large probability ($P_{thick}/P_{thin} = 6482$) to be in the thick disk with a much higher expected maximal height ($Z_{max} = 1.8 kpc$) above the Galactic plane compared with other TESS planet host stars. Future studies of the interior structure and atmospheric properties of planets in such systems using for example the upcoming James Webb Space Telescope (JWST), can investigate the differences in formation efficiency and evolution for planetary systems between different Galactic components (thick and thin disks, and halo).

description: Non-Gaussianities of primordial perturbations in the soft limit provide the important information about the light degrees of freedom during inflation. The soft modes of the curvature perturbations, unobservable for a local observer, act as rescaling the spatial coordinates. We determine how the trispectrum in the collapsed limit is shifted by the rescaling due to the soft modes. We find the form of the inequality between $f_{\rm NL}$ and $τ_{\rm NL}$ parameters is not affected by the rescaling, demonstrating that the role of the inequality as an indicator of the light degrees of freedom remains intact. We also comment on the local observer effect on the consistency relation for ultra slow-roll inflation.

As the materials used raw data from purposely selected farms in Wielkopolska. In the farms of economic size to 25 thousand euro EU subsidies play a leading role in shaping their economic situation. Unfortunately, even the large role of EU support can not be enough to change the economic situation of such households in order to gain a new and better opportunities for development. In the long term, especially very small farms, are threatened cessation of farming activities, which may be the advantage that in this way will be launched on a larger scale agrarian transformation process in Polish agriculture.
title: Strategy, culture and school development planning: a case study of staff perspectives in a secondary school
Creators: name: Jones, Stuart
Publisher: name: The Open University
Year: 2002

description: This case study is concerned with the perspectives of staff and governors in the secondary school where the researcher works as deputy head. The focus of the inquiry is school development planning and its relationship to wider strategic planning. The study further explores the School's culture and organisational structure in order to contextualise the findings and examine the School's capacity for change. The author considers the difficulties of conducting case study research in one's own place of work and utilises a range of research instruments to improve the validity of the research approach. These include questionnaires and interview schedules designed by the researcher, together with research resources designed for the Improving the Quality of Education for All (IQEA) school improvement project and the Improving School Effectiveness Project (ISEP). The study concludes that the School's development plan is generally considered to provide a sense of direction for the School but that there is little evidence of direct engagement with the plans produced. The senior team are perceived to provide purposeful leadership and the School's development structure, i.e. its capacity for improvement, is strong but there are concerns amongst many staff that decision-making is insufficiently collegiate. The author argues that this lack of involvement in key decision-making is the foundation for a model of strategy development that does not provide an authentic shared vision for the School as a whole. The School's aspirations to become a 'learning organisation' are compromised by a political structure that does not develop leadership density across the staff team. It is argued that the complexity and ambiguity of the School's culture, as reflected by the perspectives of its staff and governors, challenges the credentials of technicist models of strategic planning within this context. The result of an essentially top-down approach to strategy formation is a staff team who partially disengage themselves from strategic implementation, i.e. the school development planning process. From consideration of both the value and the constraints and limitations of this research study, the author concludes that there is a need for further case studies that explore the complexity and contradiction of the school setting and, in particular, action research studies that help the reader to understand the dynamic reality of school management from the perspectives of the practitioners themselves.

description: By explicitly computing wavefunction overlap via exact diagonalization in finite systems, we provide evidence indicating that, in the limit of strong coupling, i.e., $Δ/t \to \infty$, the ground state of the Gutzwiller-projected BCS Hamiltonian (accompanied by proper particle-number projection) is identical to the exact ground state of the 2D antiferromagnetic Heisenberg model on the square lattice. This identity is adiabatically connected to a very high overlap between the ground states of the projected BCS Hamiltonian and the t-J model at moderate doping.

description: We develop and demonstrate a new protocol that allows sensing of magnetic fields in an extra-ordinary regime for atomic magnetometry. Until now, the demonstrated bandwidth for atomic magnetometry has been constrained to be slower than the natural precession of atomic spins in a magnetic field---the Larmor frequency. We demonstrate a new approach that tracks the instantaneous phase of atomic spins to measure arbitrarily modulated magnetic fields with frequencies up to fifty times higher than the Larmor frequency. By accessing this regime, we demonstrate magnetic-field measurements across four decades in frequency up to 400 kHz, over three orders of magnitude wider than conventional atomic magnetometers. Furthermore, we demonstrate that our protocol can linearly detect transient fields 100--fold higher in amplitude than conventional methods. We highlight the bandwidth and dynamic range of the technique by measuring a magnetic field with a broad and dynamical spectrum.
An efficient unit cell based numerical model for continuum representation of fabric systems
Creators: name: Shahkarami Noori, Ali
Publisher: name: University of British Columbia
Year: 2010

description: Flexible personal armour systems are used everyday by police forces, military personnel, paramedics, and others in their line of duty. The introduction of high-performance polymer-based fibres and yarns has paved the way for the design of lightweight, yet strong body armours that can defeat a wide range of threats. However, despite the relatively high cost of materials used in bullet resistant vests, their design is completely based on experiments. Addition of simulation capability to the design process of bullet resistant vests should introduce significant savings in the time and cost associated with this activity and lead to more optimized armour systems. A novel numerical approach is introduced in this thesis that is comprised of two distinct numerical models developed in parallel and verified against each other. Experimental data are used to characterize the behaviour of fabrics and to validate the predictions of the numerical models. This combination of the numerical and experimental efforts has resulted in a unique modelling technique to capture the deformational response of fabric panels. A detailed 3D model of the fabric unit cell is created to investigate the interaction of the crossing yarns under extensional in-plane displacements. This continuum-based model explicitly considers the geometry of the yarns as an assembly of solid and bar elements and upon successful calibration, predicts the response of the fabric unit cell under the applied displacements. An efficient 2D shell crossover model is also developed that implicitly incorporates the extensional and shearing response of the crossing yarns. The governing constitutive equations for this shell element are derived considering sinusoidal compressible yarns subjected to symmetric displacements in the fabric’s plane. The efficient shell elements are used to create finite element models of fabric under static and dynamic loading scenarios. Simulations of single and multi-ply fabric targets subjected to impact are carried out and the model predictions are compared against the data from instrumented ballistic experiments. The model is found to be successful in capturing the deformational behaviour of fabric targets. Parametric analysis is performed on various geometric and mechanical properties of the fabric to investigate the sensitivity of its response to such values. Recommendations are made for setting up models of fabric to be used in industrial design process, in order to make the approach available to armour designers.

description: We present in this talk a model based on SO(10) x SU(2)_{F} having symmetric mass textures with 5 zeros constructed by us recently. The symmetric mass textures arising from the left-right symmetry breaking chain of SO(10) give rise to good predictions for the masses, mixing angles and CP violation measures in the quark and lepton sectors (including the neutrinos), all in agreement with the most up-to-date experimental data within 1 sigma. Various lepton flavor violating decays in our model are also investigated. Unlike in models with lop-sided textures, our prediction for the decay rate of mu -> e gamma is much suppressed and yet it is large enough to be probed by the next generation of experiments. The observed baryonic asymmetry in the Universe can be accommodated in our model utilizing soft leptogenesis.

description: High-fidelity polarization-entangled photons are a powerful resource for quantum communication, distributing entanglement and quantum teleportation. The Bell-CHSH inequality $S\leq2$ is violated by bipartite entanglement and only maximally entangled states can achieve $S=2\sqrt{2}$, the Tsirelson bound. Spontaneous parametric down-conversion sources can produce entangled photons with correlations close to the Tsirelson bound. Sagnac configurations offer intrinsic stability, compact footprint and high collection efficiency, however, there is often a trade off between source brightness and entanglement visibility. Here, we present a Sagnac polarization-entangled source with $2\sqrt{2}-S=(5.65\pm0.57)\times10^{-3}$, on-par with the highest values recorded, while generating and detecting $(4660\pm70)$ pairs/s/mW, which is a substantially higher brightness than previously reported for Sagnac sources and around two orders of magnitude brighter than for traditional cone sources with the highest $S$ parameter. Our source records $0.9953\pm0.0003$ concurrence and $0.99743\pm0.00014$ fidelity to an ideal Bell state. By studying systematic errors in Sagnac sources, we identify that the precision of the collection focal point inside the crystal plays the largest role in reducing the $S$ parameter in our experiment. We provide a pathway that could enable the highest $S$ parameter recorded with a Sagnac source to-date while maintaining very high brightness.

description: We present in this talk the one-loop electroweak precision constraints in the Littlest Higgs model, including the logarithmically enhanced contributions from both fermion and scalar loops. We find the one-loop contributions are comparable to the tree level corrections in some regions of parameter space. A low cutoff scale is allowed for a non-zero triplet VEV. Constraints on various other parameters in the model are also discussed. The role of triplet scalars in constructing a consistent renormalization scheme is emphasized.

This is a low metallicity (~10% solar) HII galaxy which is undergoing a burst of star formation of <5 Myr age. One possible scenario that explains the emission line spectrum of the Lynx arc, the large strength of the nitrogen lines and the HeII emission is that the object has experienced a merger event that has triggered a burst of star formation. WR stars have formed that contribute to a fast enrichment of the ISM and its overabundance of nitrogen.

description: The human factor plays now an important role in the development of agriculture and rural areas. The importance of human capital means that it is the main driving force of competitive advantage, contributing to the shaping of farms on the market. The aim of study was to determine the importance of human capital in the shaping of economic efficiency of dairy farms. Farms were assigned to groups depending on the region, level education or age of owners. Among the managers of surveyed farms, more than a half (52.27%) were people with secondary (40.15%) or higher education (12.12%). Farmers with primary education constituted 5.3% of the surveyed population. Net farm income in group of farmers with higher education averaged 5030.94 PLN/ cow and 0.68 PLN/l milk. The lowest economic efficiency was observed in farms whose owners had about 30 years ((2960 PLN/cow i 0.44 PLN/l milk). Agricultural income of farmers over the age of 60 years averaged 4890 PLN/cow and 0.78 PLN/l milk. In conclusion, farmers having higher education should know that they have the highest possibility to bring new solutions to agriculture, building on what they learned during their studies. They have the highest knowledge about how to create multifunctional development in rural areas.

description: Local topological charge structure in the 2D CP(N-1) sigma models is studied using the overlap Dirac operator. Long-range coherence of topological charge along locally 1D regions in 2D space-time is observed. We discuss the connection between these results and the recent discovery of coherent 3D sheets of topological charge in 4D QCD. In both cases, coherent regions of topological charge form along surfaces of approximmate codimension 1.

description: We consider gravity from the quantum field theory point of view and introduce a natural way of coupling gravity to matter by following the gauge principle for particle interactions. The energy-momentum tensor for the matter fields is shown to be conserved and follows as a consequence of the dynamics in a spontaneously broken SO(3,2) gauge theory of gravity. All known interactions are described by the gauge principle at the microscopic level.

description: In this article, we provide theoretical support for the use of geometric measures of nonclassicality as a general tool to identify quantum phase transitions. We argue that divergences in the susceptibility of any geometric measure of nonclassicality are sufficient conditions to identify phase transitions at arbitrary temperature. This establishes that geometric measures of nonclassicality, in any quantum resource theory, are generic tools to investigate phase transitions in quantum systems. At zero temperature, we show that geometric measures of quantum coherence are especially useful for identifying first order quantum phase transitions, and can be a particularly robust alternative to other approaches employing measures of quantum correlations.

Coarse-graining the distribution function of cold dark matter II
Creators: name: Henriksen, R. N.
Publisher: name: arXiv
Year: 2004

description: We study analytically the coarse and fine-grained distribution function established by the self-similar infall of collisionless matter. We find this function explicitly for isotropic and spherically symmetric systems in terms of cosmological initial conditions. The coarse-grained function is structureless and steady but the familiar phase space sheet sub-structure is recovered in the fine-grained limit. By breaking the self-similarity of the halo infall we are able to argue for a central density flattening. In addition there will be an edge steepening. The best fitting analytic density function is likely to be provided by a high order polytrope fit smoothly to an outer power law of index -3 for isolated systems. There may be a transition to a -4 power law in the outer regions of tidally truncated systems. We find a progressive central flattening that is expected to end either in the non-singular isothermal sphere, or in non-singular metastable polytropic cores. Therefore a collisionless system may pass through a family of polytropes of increasing order, finally approaching the limit of the non-singular isothermal sphere, if the `violent' collective relaxation is frequently re-excited by `merger' events. Our results suggest that no physics beyond that of the moderate collective relaxation often known as `violent relaxation' (due we think to wave-particle scattering) is necessary to explain the nature of dark matter density profiles.

description: The aim of the article was to assess the level and dynamics of consumption deficiency of various classes of food products across socio-economic groups of Polish households in 2005-13. The research drew on the microdata from the Social Diagnosis studies of 2005, 2007, 2009, 2011, and 2013. All considered food classes showed the lowest level of deficiency among self-employed, followed by employees and farmers, a relatively high one among retirees and pensioners, and the highest among the living on unearned sources. The most acute deficiencies involved fresh and processed fish, and despite notable improvement over the analyzed period, still in 2013 almost one in four farmer, retiree, or pensioner households, and one in two living on unearned sources, had to forgo the expense due to financial constraints.

description: Die vorliegende Arbeit beschäftigt sich mit der Problematik des Hochwassers in Verbindung mit dem experimentellen Bauen in gefährdeten Regionen. In den letzten Jahren gab es einen enormen Anstieg der globalen Bedrohung durch Hochwasser. Die Hochwasserkatastrophen forderten Schäden in Millionenhöhe, Österreich nicht ausgenommen. Es gibt bereits Länder, welche zunehmend mit angepassten und experimentellen Bauformen auf die Hochwasserproblematik reagieren. Österreich setzte diverse Maßnahmen um Städte vor dem Hochwasser zu schützen. Einerseits wurden Schutzwände errichtet, zur Trennung von Stadt und Fluss, andererseits wurden Bauverbotszonen in gefährdeten Regionen erlassen. Hiermit wird allerdings keine nachhaltige Lösung des Problems erwirkt. Warum kämpfen wir gegen das Wasser, wenn wir darauf schwimmen können? Das Ziel dieser Masterarbeit ist es, einen ersten Lösungsvorschlag für Österreich zu entwickeln, welcher Retentionsflächen* mit sicherem Bauland kombiniert. Dieses Konzept ist an jedem Ort mit dieser Problematik anwendbar und individuell planbar. Mein Ziel ist es, ein universell nutzbares Konzept zu entwickeln, welches das Bauen in hochwassergefährdeten Regionen ermöglicht und die Qualitäten der wechselnden Landschaft unterstreicht.
description: In this thesis I focussed on flooding and building in dangerous areas with new and experimental building methods. In the last few years floodings acculmulated significantly. The result is an increasing global danger in terms of flood losses, also including Austria. There are countries which have already dealt with building in flood affected areas and tried out different solutions. There are some good solutions concerning flooding danger in Austria like protection walls or red zones, where building is prohibited. Even though these arrangements are not sustainable enough when it comes to future perspectives. Why fighting against the water, when you can adjust to it? The aim of this master thesis is to figure out a new and experimental way of dealing with flooding in Austria. Furthermore it shows a different perspective of flooding with its positive aspects such as the transforming landscape. The concept includes a building solution combined with a suggestion concerning the surrounding landscape.

description: The aim of the paper was to present and evaluate changes in labor productivity, assets productivity and capital resources efficiency of Polish dairy sector in the period 2007-2014. The analyses was made with selected indicators, calculated on the basis of published and unpublished CSO data. The analyses showed that in the analyzed period positive changes have occurred in dairy sector, that reflects the growth of labor productivity and technical devices improvement. Unfortunately the dairy enterprises were unable to permanently improve the assets productivity and the capital resources efficiency. Productivity indicators of total assets and capital assets decreased, as well as indicators of capital resource efficiency measured both by gross value added and the operating surplus.

description: The study attempts to analyze the impact of marketing on improving the competitiveness of organic products from the point of view of suppliers and customers. Studies have shown that marketing activities are not fully adapted to the requirements and expectations of consumers. Both groups of respondents have different ideas about marketing of organic products. On the one hand, consumers declared that for them the most important element of marketing is the price that is too high and thus affects the level of purchased organic products. On the other hand seller, unaware of the need for Markdown, thought it tastings are the most effective form of promotion of their products. Communication is needed between the supplier and the recipient of this type of product range, marketing efforts to be effective. The prerequisite is to know the expectations and preferences of consumers and lead marketing strategy oriented customer.

Higgs-Portal Dark Matter in Nonlinear MSSM

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Supersymmetric (SUSY) extension of the Standard Model (SM) is a primary candidate for new physics beyond the SM. If SUSY breaking scale is very low, for example, the multi-TeV range, and the SUSY breaking sector, except for the goldstino (gravitino), is decoupled from the low energy spectrum, the hidden sector effect in the minimal SUSY SM (MSSM) is well described by employing the goldstino chiral superfield ($X$) with the nilpotent condition of $X^2=0$. Although this so-called "nonlinear MSSM" (NL-MSSM) provides a variety of interesting phenomenologies, there is a cosmological problem that the lightest superpartner gravitino is too light to be the major component of the dark matter (DM) in our universe. To solve this problem, we propose a minimal extension of the NL-MSSM by introducing a parity-odd SM singlet chiral superfield ($Φ$). We show that the interaction of the scalar component in $Φ$ with the MSSM Higgs doublets is induced after eliminating F-component of the goldstino superfield and the lightest real scalar in $Φ$ plays the role of the Higgs-portal DM. With a suitable choice of the model parameters, a successful Higgs-portal DM scenario can be realized while achieving the SM-like Higgs boson mass of 125 GeV from the tree-level Higgs potential through the multi-TeV SUSY breaking effect.
