Mass and magnetic moments of the heavy flavored baryons with in light cone QCD sum rules
Abstract Inspired by the results of recent experimental discoveries for charm and bottom baryons, the masses and magnetic moments of the heavy baryons with J P ...

Non-universality of transverse momentum dependent parton distribution functions
Abstract In the field theoretical description of hadronic scattering processes, single transverse-spin asymmetries arise due to gluon initial and final state interactions. These interactions lead to process dependent Wilson lines in the operator...

Transient Power Quality Recognition Based on BP Neural Network Theory
Abstract This paper researches on the combination between wavelet transformation and neural network to realize the transient power quality disturbance signals’ recognition. Firstly, the mathematical models of five kinds of transient disturbance...

MOEMS-Based Scanning Light Barrier
Abstract This work deals with the development of a novel MOEMS-based platform for miniaturised 1D or 2D light barrier systems. As outlined below, such a device could be used to project a classical linear light barrier, but could equally be used to...

A note on fuzzy best approximation using Chebyshev’s polynomials
Abstract This paper deals with the best approximation for fuzzy valued functions using Chebyshev nodes. We prove a result on the best near-minimax approximation in the fuzzy sense. As an application, Runge’s phenomenon is fuzzified in two different...

Tubular solutions of Dirac–Born–Infeld action on Dp-brane background
Abstract We use the Dirac–Born–Infeld action on Dp-brane background to find the tubular bound state of a D2 with m D 0 -branes and n fundamental strings....

Towards resolution of hierarchy problems in a cosmological context
Abstract A cosmological scenario is proposed, which simultaneously solves the mass hierarchy and the small dark energy problem. In the present scenario an effective gravity mass scale (inverse of the Newton's constant) increases during the...

Tilt and phantom cosmology
Abstract We show that in tilting perfect fluid cosmological models with an ultra-radiative equation of state, generically the tilt becomes extreme at late times and, as the tilt instability sets in, observers moving with the tilting fluid will...

Dark matter disc enhanced neutrino fluxes from the Sun and Earth
Abstract As disc galaxies form in a hierarchical cosmology, massive merging satellites are preferentially dragged towards the disc plane. The material accreted from these satellites forms a dark matter disc that contributes 0.25–1.5 times the...

Hawking radiation of Dirac particles from Kerr–AdS black hole in five dimensions
Abstract By constructing a set of appropriate matrices γ μ for general covariant Dirac equation, we further extend fermion ...

The generalized second law in universes with quantum corrected entropy relations
Abstract We apply the generalized second law of thermodynamics to discriminate among quantum corrections (whether logarithmic or power-law) to the entropy of the apparent horizon in spatially Friedmann–Robertson–Walker universes. We use the...

Lorentz violation and the speed of gravitational waves in brane-worlds
Abstract Lorentz violation in a brane-world scenario is presented and used to obtain a relationship between the speed of gravitational waves in the bulk and that on the brane. Lorentz violating effects would manifest themselves in gravitational...

Pseudo-Newtonian potential for charged particle in Kerr–Newman geometry
Abstract We consider the equatorial circular motion of a test particle of specific charge q ≪ m in the Kerr–Newman geometry of a rotating charged black...

The neutron/proton ratio of squeezed-out nucleons and the high density behavior of the nuclear symmetry energy
Abstract Within a transport model it is shown that the neutron/proton ratio of squeezed-out nucleons perpendicular to the reaction plane, especially at high transverse momenta, in heavy-ion reactions induced by high energy neutron-rich nuclei can be ...

Effect of absorptive corrections on inclusive parton distributions
Abstract We study the effect of absorptive corrections due to parton recombination on the parton distributions of the proton. A more precise version of the GLRMQ equations, which account for non-linear corrections to DGLAP evolution, is derived. An...

A case of subdominant/suppressed “high energy” contribution to the baryon asymmetry of the Universe in flavoured leptogenesis

Photons from dark matter in a (non-universal) extra dimension model
Abstract We study the multi-wavelength signal induced by pairs annihilations at the galactic center (GC) of a recently proposed dark matter (DM) candidate. The weakly interacting massive particle (WIMP) candidate, named ...

Constraining slow-roll inflation in the presence of dynamical dark energy
Abstract In this Letter we perform a global analysis of the constraints on the inflationary parameters in the presence of dynamical dark energy models from the current observations, including the three-year Wilkinson Microwave Anisotropy Probe...
