Observation suggests ∼80% of all the mass of the universe currently comes from a nonluminous, nonbaryonic form of matter known as dark matter. Currently, WIMPs are one of the most favored models to explain the missing mass of the universe. XENON100, a detector experiment in Gran Sasso, has place the best upper limits for the cross section at ∼ 10−44cm2 for a 50GeV/c mass WIMP. Since detection o...

In twin Higgs models that contain the minimal particle content required to address little hierarchy problem (i.e., fraternal models), tau has been identified as a promising candidate for dark matter. this class of scenarios, however, elastic scattering cross section with nuclei exceeds bounds from XENON1T and other recent direct detection experiments. paper, we propose modification scenario cal...

The U$\mu\nu$SSM is a $U(1)'$ extension of the $\mu\nu$SSM supersymmetric model, where baryon-number-violating operators as well explicit mass terms are forbidden, and potential domain wall problem avoided. gauge anomaly-cancellation conditions impose presence exotic quark superfields in spectrum models, allow several singlet under standard model group, addition to right-handed neutrino superfi...

The annihilation of neutralino dark matter may result in observable signals in different wavelength. In the present paper we will discuss the effect of neutralino annihilation in the halo of our Galaxy and in its center. According to high resolution cold dark matter simulations, large virialized halos are formed through the constant merging of smaller halos appeared at previous times. At each e...

With the availability of affordable large-scale monitors and powerful projector hardware, an increasing variety of display configurations can be found in our everyday environments, such as office spaces and meeting rooms. These emerging display environments combine conventional monitors and projected displays of different size, resolution, and orientation into a common interaction space. Howeve...

We discuss the production of dark matter with mass order 10--100 TeV and $\mathcal{O}(1)$ couplings to standard model, a scenario we refer as ``mesotuned WIMP.'' Given lack new physics observed at LHC, indicating live in world some degree fine-tuning, this scale is natural expect particles appear. However, range large difficult produce relic abundance via usual mechanisms. Here nonthermal show ...

Detection rates for the elastic and inelastic scattering of weakly interacting massive particles (WIMPs) off 23Na are calculated within framework Deformed Shell Model (DSM) based on Hartree-Fock states. At first, spectroscopic properties detector nucleus, like energy spectra magnetic moments, evaluated compared with experimental data. Following good agreement these results, DSM wave functions u...
