Entropic cosmology: A unified model of inflation and late-time acceleration
Abstract Holography is expected as one of the promising descriptions of quantum general relativity. We present a model for a cosmological system involving two holographic screens and find that their equilibrium exactly yields a standard...

Dynamical stabilization of runaway potentials at finite density
Abstract We study four-dimensional non-Abelian gauge theories with classical moduli. Introducing a chemical potential for a flavor charge causes moduli to become unstable and start condensing. We show that the moduli condensation in the presence of...

Nuclear shadowing in neutrino–nucleus deeply inelastic scattering
Abstract In the framework of the collinear factorized pQCD approach we calculate the small-x B process-dependent nuclear modification to the structure functions measured in...

Lovelock black holes with a power-Yang–Mills source
Abstract We consider the standard Yang–Mills (YM) invariant raised to the power q, i.e., ( F ...

Non-linear evolution of pomeron and odderon in momentum space
Abstract The small x evolution of the QCD pomeron and the QCD odderon is investigated in the mean field limit of the color glass condensate. The resulting system of coupled non-linear evolution equations is transformed to the momentum space and...

Constraints on hybrid inflation from flat directions in supersymmetry
Abstract We examine the constraints on F-term hybrid inflation by considering the flat directions in the Minimal Supersymmetric Standard Model (MSSM). We find that some coupling terms between the flat direction fields and the field which dominates...

Extracting γ from Bd0(t)→D(∗)+D(∗)− and Bd0→Ds(∗)+D(∗)− decays
Abstract We show that the CP phase γ can be obtained from measurements of Bd 0(t)→D(∗)+D(∗)− and Bd 0→Ds (∗)+D(∗)− . These decays are...

Natural μ and Bμ in gauge mediation
Abstract We propose a natural solution to the μ problem in gauge mediation. It relies on the logarithmic dependence of the effective Kähler potential on the messenger threshold superfield X. Thus, μ and Bμ naturally arise at one and two loops,...

Thermodynamics of warped AdS3 black hole in the brick wall method
Abstract The statistical entropy of a scalar field on the warped AdS3 black hole in the cosmological topologically massive gravity is calculated based on the brick-wall method, which is different from the Wald's entropy formula giving the modified...

Gribov horizon in the presence of dynamical mass generation in Euclidean Yang–Mills theories in the Landau gauge
Abstract The infrared behavior of the gluon and ghost propagators is analyzed in Yang–Mills theories in the presence of dynamical mass generation in the Landau gauge. By restricting the domain of integration in the path-integral to the Gribov region ...

Sweet spot supersymmetry and composite messengers
Abstract Sweet spot supersymmetry is a phenomenological effective Lagrangian of weak scale supersymmetry with a certain set of natural assumptions. This framework is designed to avoid problems in low-energy phenomenology and cosmology of...

Muon Sites Estimation in La2Cu04 and A New Vanadium Cluster Compound, V4S9Br4, using Electronic and Nuclear Dipole Field Calculations
Abstract A new positive muon position in La2CuO4 is suggested from electronic and nuclear dipoles simulations. The muon site was found to be close to the center of a triangle plane of the CuO6 octahedral that was formed by the apical and two...
