Boson stars in SU(2) Yang–Mills scalar field theories
Abstract We present new spherically symmetric solutions of an SU(2) Einstein–Yang–Mills model coupled to a doublet of scalar fields. Sequences of asymptotically flat, Yang–Mills boson star-type configurations are constructed numerically by...

Threshold corrections to mb and the bb̄→H0i production in CP-violating SUSY scenarios
Abstract The inclusion of supersymmetric threshold corrections to the b-quark mass has dramatic consequences in scenarios with large CP-mixing effects in the Higgs sector. In particular, when the phase of the combination M ...

Closer towards inflation in string theory
Abstract In brane inflation, the relative brane position in the bulk of a brane world is the inflaton. For branes moving in a compact manifold, the approximate translational (or shift) symmetry is necessary to suppress the inflaton mass, which then...

The electro-disintegration of few body systems revisited
Abstract Recent studies of the electro-disintegration of the few body systems at JLab have revived the field. Not only recoil momentum distributions have been determined in a single shot. But also they confirm that the diagrammatic approach, which I ...

Parameters in a class of leptophilic dark matter models from PAMELA, ATIC and FERMI
Abstract In this work we study a class of leptophilic dark matter models, where the dark matter interacts with the standard model particles via the U ...

Effect of sodium substitution on the structural, magnetic and magnetocaloric properties of La0.5Ca0.5MnO3 perovskite manganites
Abstract The perovskite-type La0.5Ca0.5−x Na x MnO3 (0.05≤x≤0.2) ceramic samples were prepared using the solid-state reaction at high temperature. The X-ray powder diffraction...

Simulation of electron-beam sustained discharge laser
Abstract The complex program simulating processes in the electron-beam sustained discharge laser (EBSL) is created. It simultaneously models processes of electron beams spread in electron accelerator, elements of a design and the flash chamber under ...

Statistical interpretation of the spatial distribution of current 130 GeV γ-ray line signal within the dark matter annihilation scenario
Abstract Recently, several groups identified a tentative γ-ray line signal with energy ∼130 GeV in the central Galaxy from the Fermi-LAT data. Such a γ-ray line can be interpreted as the signal of dark matter annihilation. However, the offset ∼220...

Light sterile neutrino in the minimal extended seesaw
Abstract Motivated by the recent observations on sterile neutrinos, we present a minimal extension of the canonical type-I seesaw by adding one extra singlet fermion. After the decoupling of right-handed neutrinos, an eV-scale mass eigenstate is...

Wavelet Based Spectrum Sensing Techniques in Cognitive Radio
Abstract For cognitive radio the main issue is to sense and identify all spectrum holes present in the environment. In this paper we are proposing a wavelet approach for spectrum sensing and spectrum hole identification. We will apply wavelet...

Spontaneous gauge symmetry breaking in a non-supersymmetric D-brane model
Abstract We investigate a D-brane system in which spontaneous gauge symmetry breaking occurs. The system consists of four D3-branes and three anti-D7-branes at C ...
