Magnetic string coupled to nonlinear electromagnetic field
Abstract We introduce a class of rotating magnetically charged string solutions of the Einstein gravity with a nonlinear electrodynamics source in four dimensions. The present solutions has no curvature singularity and no horizons but has a conic...

Virtual coupling potential for elastic scattering of 10,11Be on proton and carbon targets
Abstract The 10,11Be(p, p) and (12C, 12C) reactions were analyzed to determine the influence of the weak binding energies of exotic nuclei on their interaction potential. The elastic cross sections were measured at GANIL in inverse kinematics using...

Universal seesaw from left–right and Peccei–Quinn symmetry breaking
Abstract To generate the lepton and quark masses in the left–right symmetric models, we can consider a universal seesaw scenario by integrating out heavy fermion singlets which have the Yukawa couplings with the fermion and Higgs doublets. The...

Decay constants of charm and beauty pseudoscalar heavy–light mesons on fine lattices
Abstract We compute decay constants of heavy–light mesons in quenched lattice QCD with a lattice spacing of a ≃ 0.04 fm ...

Effect of electric field of the electrosphere on photon emission from quark stars
Abstract We investigate the photon emission from the electrosphere of a quark star. It is shown that at temperatures T ∼ 0.1 – 1 ...

Comment on: “The Casimir force on a piston in the spacetime with extra compactified dimensions” [Phys. Lett. B 668 (2008) 72]
Abstract We offer a clarification of the significance of the indicated paper of H. Cheng. Cheng's conclusions about the attractive nature of Casimir forces between parallel plates are valid beyond the particular model in which he derived them; they...

Coupling of a vector gauge field to a massive tensor field
Abstract We consider a four-dimensional model in which the field strength associated with a vector gauge field is coupled directly to an antisymmetric tensor field and a pseudoscalar mass term for the tensor field appears. Analysis of the constraint ...

Evidence for quark spin-flip in pomeron exchange
Abstract Spin-parity analyses of the ωπ system in the reaction γ p → ( ω π ) ...

Polyakov loop and the color–flavor locked phase of quantum chromodynamics
Abstract We consider the Polyakov–Nambu–Jona-Lasinio model with three massless quarks at high density and moderate temperature in the superconductive color–flavor locking phase. We compute the critical temperature ...

Novel effects of electromagnetic interaction on the correlation of nucleons in nuclear matter
Abstract The electromagnetic (EM) interactions between charged protons on the correlations of nucleons are discussed by introducing the Anderson–Higgs mechanism of broken U ( 1 ...

Dielectron and diphoton channels in 2HDM
Abstract It was observed recently that [L. Randall, Mark B. Wise, arXiv: 0807.1746 [hep-ph]], any particle in the Standard Model cannot decay to e + ...

Electroweak scale neutrinos and decaying dark matter
Abstract We explore the scalar phenomenology of a model of electroweak scale neutrinos that incorporates the presence of a lepton number violating singlet scalar. An analysis of the pseudoscalar-Majoron field associated to this singlet field is...

The effect of curvature in thawing models
Abstract We study the evolution of spatial curvature for thawing class of dark energy models. We examine the evolution of the equation of state parameter, w ϕ ...

Acceleration of a spherical brane-universe
Abstract The model where the universe is considered as an expanding spherical 3-brane allows us to explain its expansion rate without a dark energy component. In this scenario the computed redshift that corresponds to the transition from cosmic...

Inverted neutrino mass hierarchy and new signals of a chromophobic charged Higgs at the Large Hadron Collider
Abstract We explore the signals of a charged Higgs arising in a two Higgs doublet model respecting SU ( 2 ...

Note on “Domain wall universe in the Einstein–Born–Infeld theory” [Phys. Lett. B 679 (2009) 160]
Abstract The interaction between bulk and dynamic domain wall in the presence of a linear/non-linear electromagnetism make energy density, tension and pressure on the wall all variables, depending on the wall position. In Lee et al. (2009) [1] this...

Implications of catalyzed BBN in the CMSSM with gravitino dark matter
Abstract We investigate gravitino dark matter scenarios in which the primordial 6Li production is catalyzed by bound-state formation of long-lived negatively charged particles X ...

Kink instability and stabilization of the Friedmann universe with scalar fields
Abstract The evolution of weak discontinuity is investigated in the flat FRW universe with a single scalar field and with multiple scalar fields. We consider both massless scalar fields and scalar fields with exponential potentials. Then we find...
