Interacting viscous mixtures
Abstract Gravitational and hydrodynamical perturbations are analysed in a relativistic plasma containing a mixture of interacting fluids characterized by a non-negligible bulk viscosity coefficient. The energy–momentum transfer between the...

Simple model for (3+2) neutrino oscillations
Abstract We formulate a set of naturalness criteria for sterile neutrinos (ν′) to be light, needed for reconciling the LSND neutrino anomaly with the other neutrino data. A light sterile neutrino becomes as natural as the light active neutrinos if...

Inflation and reheating in induced gravity
Abstract Inflation is studied in the context of induced gravity (IG) γ σ 2 R ...

Matrix oscillator and Calogero-type models
Abstract We study a single matrix oscillator with the quadratic Hamiltonian and deformed commutation relations. It is equivalent to the multispecies Calogero model in one dimension, with inverse-square two-body and three-body interactions....

The general behavior of NLO unintegrated parton distributions based on the single-scale evolution and the angular ordering constraint
Abstract To overcome the complexity of generalized two hard scale ( k t , μ ...

Gauge invariant formulation of massive totally symmetric fermionic fields in (A)dS space
Abstract Massive arbitrary spin totally symmetric free fermionic fields propagating in d-dimensional (anti-)de Sitter space–time are investigated. Gauge invariant action and the corresponding gauge transformations for such fields are proposed. The...

Soft leptogenesis and gravitino dark matter in gauge mediation
Abstract We study soft leptogenesis in gauge mediated supersymmetry breaking models with an enhanced A-term for the right-handed neutrino. We find that this scenario can explain the baryon asymmetry of the present universe, consistently with the...

Color sextet vector bosons and same-sign top quark pairs at the LHC
Abstract We investigate the production of beyond-the-standard-model color sextet vector bosons at the Large Hadron Collider and their decay into a pair of same-sign top quarks. We demonstrate that the energy of the charged lepton from the top quark...

Searching for an extra neutral gauge boson from muon pair production at LHC

Model-independent resonance parameter extraction from the trace of K and T matrices
Abstract A model-independent method for the determination of resonance parameters as K-matrix pole parameters from a T matrix is presented. The method is based on eliminating the dependence on the choice of channel basis by analyzing the trace of...

Finite energy chiral sum rules in QCD
Abstract The saturation of QCD chiral sum rules of the Weinberg-type is analyzed using ALEPH and OPAL experimental data on the difference between vector and axial-vector correlators (V–A). The sum rules exhibit poor saturation up to current energies ...

Quantum UV/IR relations and holographic dark energy from entropic force
Abstract We investigate the implications of the entropic force formalism proposed by Verlinde. We show that an UV/IR relation proposed by Cohen et al., as well as an uncertainty principle proposed by Hogan can be derived from the entropic force...

Contribution of asymmetric strange–antistrange sea to the Paschos–Wolfenstein relation
Abstract The NuTeV Collaboration reported a value of sin2 θ w measured in neutrino–nucleon deep inelastic scattering, and found that the value is three standard ...

Drell–Hearn–Gerasimov sum-rule for the deuteron in nuclear effective field theory
Abstract The Drell–Hearn–Gerasimov sum rule for the deuteron is studied in nuclear effective field theory. The low-energy theorem for the spin-dependent Compton amplitude f ...

Can dissipation prevent explosive decomposition in high-energy heavy ion collisions?
Abstract We discuss the role of dissipation in the explosive spinodal decomposition scenario of hadron production during the chiral transition after a high-energy heavy ion collision. We use a Langevin description inspired by microscopic...

Pion wave function from lattice QCD vs. chiral quark models
Abstract We analyze the equal-time Bethe–Salpeter quark wave function of the pion obtained from a quenched lattice QCD calculation with delocalized quark interpolators. We find that the result agrees remarkably well with the predictions of the...
