Nuclear transparencies in relativistic A(e,e′p) models
Abstract Relativistic and unfactorized calculations for the nuclear transparency extracted from exclusive A(e,e′p) reactions for 0.3⩽Q 2⩽10 (GeV/c)2 are presented for the target nuclei C, Si, Fe and Pb. For Q ...

Azimuthal asymmetry of direct photons in intermediate energy heavy-ion collisions
Abstract Hard photon emitted from energetic heavy ion collisions is of very interesting since it does not experience the late-stage nuclear interaction, therefore it is useful to explore the early-stage information of matter phase. In this work, we...

Rotating boson stars in 2+1 dimensions
Abstract We consider rotating boson star solutions in a three-dimensional anti-de Sitter spacetime and investigate the influence of the rotation on their properties. The mass and angular momentum of these configurations are computed by using the...

The reaction channels in the threshold region
Abstract The cross section for direct neutral and charged three pion production in pp interactions was measured at excess energies in the range 160–216 MeV. That comprises the first measurement of the p ...

Efficient coannihilation process through strong Higgs self-coupling in LKP dark matter annihilation
Abstract We point out that the lightest Kaluza–Klein particle (LKP) dark matter in universal extra dimension (UED) models efficiently annihilates through the coannihilation process including the first KK Higgs bosons when the Higgs mass is slightly...

On the dynamics of exotic matter: Towards creation of Perpetuum Mobile of third kind
Abstract The one-dimensional dynamics of a classical ideal ‘exotic’ fluid with equation of state p = p ( ϵ ...

Quantum critical superconductors in string theory and M-theory
Abstract We construct zero-temperature solutions of supergravity theories in five and four dimensions which interpolate between two copies of anti-de Sitter space, one of which preserves an Abelian gauge symmetry while the other breaks it. These...

An alternative interpretation of X(3872)
Abstract It is proposed that X(3872) is a vector glueball mixed with neighboring vector states of charmonium.

Another step towards a no-lose theorem for NMSSM Higgs discovery at the LHC
Abstract We show how the LHC potential to detect a rather light CP-even Higgs boson of the NMSSM, H 1 or ...

Intersection democracy for winding branes and stabilization of extra dimensions
Abstract We show that, in the context of pure Einstein gravity, a democratic principle for intersection possibilities of branes winding around extra dimensions in a given partitioning yield stabilization, while what the observed space follows is...

Have neutron stars a dark matter core?
Abstract Recent observational results for the masses and radii of some neutron stars are in contrast with typical observations and theoretical predictions for “normal” neutron stars. We propose that their unusual properties can be interpreted as the ...

Utilizing Laser Power Modulation to Investigate the Transition from Heat-Conduction to Deep-Penetration Welding
Abstract In laser welding the two regimes of heat-conduction welding and deep-penetration welding are distinguished. In order to characterize these two process regimes, the shown approach uses a sinusoidal laser power modulation together with...

Spin dependent electronic structure and level crossings as a function of magnetic field in InAs nanowire
Abstract We point out that the electric field formed in the surface inversion layer in InAs nanowires leads to effective magnetic fields, due to the Rashba effect, that are mostly aligned along the wire axis, i.e., parallel to the external magnetic...

Critical phenomena without “hyper scaling”: How is the finite-size scaling analysis of Monte Carlo data affected?
Abstract The finite size scaling analysis of Monte Carlo data is discussed for two models for which hyperscaling is violated: (i) the random field Ising model (using a model for a colloid-polymer mixture in a random matrix as a representative) (ii)...

Proximal Magnetometry of Monolayers of Magnetic Moments
Abstract We present a method to measure the magnetic properties of monolayers and ultra-thin films of magnetic material. The method is based on low energy muon spin rotation and β-detected nuclear magnetic resonance measurements. A spin probe is...

Mellin–Barnes representations of Feynman diagrams, linear systems of differential equations, and polynomial solutions
Abstract We argue that the Mellin–Barnes representations of Feynman diagrams can be used for obtaining linear systems of homogeneous differential equations for the original Feynman diagrams with arbitrary powers of propagators without recourse to...

Dynamical dark energy and spontaneously generated gravity
Abstract We study the cosmological evolution of an induced gravity model with a scale symmetry breaking potential for the scalar field and the presence of barotropic fluids. The radiation to matter transition, following inflation and reheating,...

Analysis of Neutron Induced Gamma Activity in Lowbackground Ge – Spectroscopy Systems
Abstract Neutron interactions with materials of Ge-spectroscopy systems are one of the main sources of background radiation in low-level gamma spectroscopy measurements. Because of that detailed analysis of neutron induced gamma activity in...
