Exploring the universal extra dimension at the LHC
Abstract Besides supersymmetry, the other prime candidate of physics beyond the Standard Model (SM), crying out for verification at the CERN Large Hadron Collider (LHC), is extra-dimension. To hunt for effects of Kaluza–Klein (KK) excitations of...

Natural braneworld inflation and baryogenesis
Abstract In natural inflation models, the inflaton is a pseudo Nambu–Goldstone boson and the flatness of the potential is protected by shift symmetries. In this framework, a successful inflation requires the global symmetry to be spontaneously...

Does the hard pomeron obey Regge factorisation?
Abstract While data for the proton structure function demand the presence of a hard-pomeron contribution even at quite small Q 2, previous fits to the pp and p p ̄ ...

Mass dependence of vacuum energy
Abstract The regularized vacuum energy (or energy density) of a quantum field subjected to static external conditions is shown to satisfy a certain partial differential equation with respect to two variables, the mass and the “time” (ultraviolet...

Charge distributions in transverse coordinate space and in impact parameter space
Abstract We study the charge distributions of the valence quarks inside nucleon in the transverse coordinate space, which is conjugate to the transverse momentum space. We compare the results with the charge distributions in the impact parameter...

Confinement from spontaneous breaking of scale symmetry
Abstract We show that one can obtain naturally the confinement of static charges from the spontaneous symmetry breaking of scale invariance in a gauge theory. At the classical level a confining force is obtained and at the quantum level, using a...

Vacuum expectation value of a Wegner–Wilson loop near the light-cone
Abstract Vacuum expectation values for one Wegner–Wilson loop representing a moving quark–antiquark pair are calculated in four-dimensional Euclidean and Minkowski space–time. The calculation uses gluon field strength correlators with perturbative...

Non-supersymmetric charged domain walls
Abstract We present general non-supersymmetric domain wall solutions with non-trivial scalar and gauge fields for gauged five-dimensional N = 2 ...

Discovering the Higgs bosons of minimal supersymmetry with bottom quarks
Abstract We investigate the prospects for the discovery of a neutral Higgs boson produced with one bottom quark followed by Higgs decay into a pair of bottom quarks at the CERN Large Hadron Collider (LHC) and the Fermilab Tevatron Collider. We work...

Weak basis transformations and texture zeros in the leptonic sector
Abstract We investigate the physical meaning of some of the texture zeros which appear in most of the ansatzes on leptonic masses and their mixing. It is shown that starting from arbitrary lepton mass matrices and making suitable weak basis...

Slepton production in polarized hadron collisions
Abstract We calculate cross sections and asymmetries for slepton pair production through neutral and charged electroweak currents in polarized hadron collisions for general slepton masses and including mixing of the left- and right-handed...

Photoproduction of K∗ for the study of Λ(1405)
Abstract The photo-induced K∗ vector meson production is investigated for the study of the Λ(1405) resonance. This reaction is particularly suited to the isolation of the second pole in the Λ(1405) region which couples...

Cosmic ray positron and electron excess from hidden-fermion dark matter decays
Abstract The anomalies observed in recent cosmic ray experiments seem to strongly constrain the nature of the dark matter. In this Letter, we investigate a possibility of the fermionic dark matter with a minimal extension of the standard model. We...

Supersymmetric gauged scale covariance in ten and lower dimensions
Abstract We present globally supersymmetric models of gauged scale covariance in ten, six, and four dimensions. This is an application of a recent similar gauging in three dimensions for a massive self-dual vector multiplet. In ten dimensions, we...

“T-odd effects” in unpolarized Drell–Yan scattering
Abstract We consider the leading twist “T-odd” contributions as the dominant source of the cos 2 ϕ azimuthal asymmetry in unpolarized ...

Charged gravastars admitting conformal motion
Abstract We propose a new model of a gravastar admitting conformal motion. While retaining the framework of the Mazur–Mottola model, the gravastar is assumed to be internally charged, with an exterior defined by a Reissner–Nordström instead of a...

Dark energy and QCD ghost
Abstract It has been suggested that the dark energy that explains the observed accelerating expansion of the universe may arise due to the contribution to the vacuum energy of the QCD ghost in a time-dependent background. The argument uses a...

Effects of final state interactions on charge separation in relativistic heavy ion collisions
Abstract Charge separation is an important consequence of the Chiral Magnetic Effect. Within the framework of a Multi-Phase Transport model, the effects of final state interactions on initial charge separation are studied. We demonstrate that charge ...
