Status and prospects for BSM ( (N)MSSM) Higgs searches at the LHC
Searches for Beyond the Standard Model Higgs processes in the context of
Minimal Supersymmetric Standard Model and Next to MSSM are presented. The
results are based on the first LHC run of pp collision data recorded by the
ATLAS and CMS experiments at the CERN Large Hadron Collider at centre-of-mass
energies of 7 and 8 TeV, corresponding to integrated luminosities of about 5
and 20 fb respectively. Current searches constrain large parts of the
parameter space. No evidence for BSM Higgs is found.Comment: Talk presented at the International Workshop on Future Linear

Statistical Mechanics of finite arrays of coupled bistable elements
We discuss the equilibrium of a single collective variable characterizing a
finite set of coupled, noisy, bistable systems as the noise strength, the size
and the coupling parameter are varied. We identify distinct regions in
parameter space. The results obtained in prior works in the asymptotic infinite
size limit are significantly different from the finite size results. A
procedure to construct approximate 1-dimensional Langevin equation is adopted.
This equation provides a useful tool to understand the collective behavior even
in the presence of an external driving force
Examining Retirement Housing Preferences Among International Retiree Migrants
Housing demand models based on individual consumers' utility function reflect preferences about the structure and lot, neighborhood, and location as related to socioeconomic characteristics of the occupants. As a growing proportion of aging residents in many countries are undertaking late life moves, their preferences will have an influence on destination housing markets. We examine the characteristics, attitudes and preferences about retirement housing among immigrant retirees currently living in traditional housing in a retirement destination in Alicante, Spain. Using results from a survey of German and British retirees living in the region, we find through logistic regression that preference for retirement housing is associated with aging and gaining access to in-home support services.Housing preferences; Demographic trends; Seniors housing
Stochastic resonance with weak monochromatic driving: gains above unity induced by high-frequency signals
We study the effects of a high-frequency (HF) signal on the response of a
noisy bistable system to a low-frequency subthreshold sinusoidal signal. We
show that, by conveniently choosing the ratio of the amplitude of the HF signal
to its frequency, stochastic resonance gains greater than unity can be measured
at the low-frequency value. Thus, the addition of the HF signal can entail an
improvement in the detection of weak monochromatic signals. The results are
explained in terms of an effective model and illustrated by means of numerical
simulations.Comment: 5 pages, 2 figure
A new div-curl result. Applications to the homogenization of elliptic systems and to the weak continuity of the Jacobian
In this paper a new div-curl result is established in an open set of
, , for the product of two sequences of vector-valued
functions which are bounded respectively in and
, with , and whose respectively
divergence and curl are compact in suitable spaces. We also assume that the
product converges weakly in . The key ingredient of the proof
is a compactness result for bounded sequences in , based on
the imbedding of into ( the
unit sphere of ) through a suitable selection of annuli on which
the gradients are not too high, in the spirit of De Giorgi and Manfredi. The
div-curl result is applied to the homogenization of equi-coercive systems whose
coefficients are equi-bounded in for some
\rho\textgreater{}{N-1\over 2} if N\textgreater{}2, or in if
. It also allows us to prove a weak continuity result for the Jacobian for
bounded sequences in satisfying an alternative assumption
to the -strong estimate of Brezis and Nguyen. Two examples show the
sharpness of the results
