Quantum theory of neutrino spin light in dense matter
Abstract We develop the quantum theory of the spin light of neutrino (SLν) exactly accounting for the effect of background matter. Contrary to the already performed studies of the SLν, in this Letter we derive expressions for the SLν rate and power...

Soft leptogenesis in Higgs triplet model
Abstract We consider the minimal supersymmetric triplet seesaw model as the origin of neutrino masses and mixing as well as of the baryon asymmetry of the Universe, which is generated through soft leptogenesis employing a CP-violating phase and a...

Electroweak symmetry breaking induced by dark matter
Abstract The mechanism behind electroweak symmetry breaking (EWSB) and the nature of dark matter (DM) are currently among the most important issues in high energy physics. Since a natural dark matter candidate is a weakly interacting massive...

Proliferation in cycle
Abstract In the contracting phase with w ≃ 0 , the scale invariant spectrum of curvature perturbation is given by the increasing mode of metric...

Thermal hadron production in relativistic nuclear collisions: The hadron mass spectrum, the horn, and the QCD phase transition
Abstract We present, using the statistical model, a new analysis of hadron production in central collisions of heavy nuclei. This study is motivated by the availability of final measurements both for the SPS (beam energies ...

Elastic scattering and total reaction cross section for the 6He + 27Al system
Abstract The elastic scattering of the radioactive halo nucleus 6He on 27Al target was measured at four energies close to the Coulomb barrier using the RIBRAS (Radioactive Ion Beams in Brazil) facility. The São Paulo Potential (SPP) was used and its ...

Finite-size effects on the phase structure of the Nambu–Jona-Lasinio model
Abstract The Nambu–Jona-Lasinio (NJL) model is one of the most frequently used four-fermion models in the study of dynamical symmetry breaking. In particular, the NJL model is convenient for that analysis at finite temperature, chemical potential...

Next-to-leading order QCD corrections to the Z boson pair production at the LHC in Randall–Sundrum model
Abstract The first results on next-to-leading order QCD corrections to production of two Z bosons in hadronic collisions in the extra dimension model of Randall and Sundrum are presented. Various kinematical distributions are obtained to order ...

First-order formalism for bent brane
Abstract This work deals with braneworld scenarios in the presence of real scalar field with standard dynamics. We show that the first-order formalism, which exists in the case of flat brane, can be extended to bent brane, for both de Sitter and...

The ambiguity-free four-dimensional Lorentz-breaking Chern–Simons action
Abstract The four-dimensional Lorentz-breaking finite and determined Chern–Simons like action is generated as a one-loop perturbative correction via an appropriate Lorentz-breaking coupling of the gauge field with the spinor field. Unlike the known...

Lifetime measurements of excited states in 17C: Possible interplay between collectivity and halo effects

Black hole and holographic dark energy
Abstract We discuss the connection between black hole and holographic dark energy. We examine the issue of the equation of state (EOS) for holographic energy density as a candidate for the dark energy carefully. This is closely related to the EOS...

Saturation and forward jets at HERA
Abstract We analyse forward-jet production at HERA in the framework of the Golec-Biernat and Wüsthoff saturation models. We obtain a good description of the forward-jet cross-sections measured by the H1 and ZEUS Collaborations in the two-hard-scale...

The gluon splitting function at moderately small x
Abstract It is widely believed that at small x, the BFKL resummed gluon splitting function should grow as a power of 1/x. But in several recent calculations it has been found to decrease for moderately small-x before eventually rising. We show that...

Chiral soliton models, large Nc consistency and the Θ+ exotic baryon
Abstract Predictions for a light collective Θ + baryon state (with strangeness +1) based on the collective quantization of chiral soliton models are shown to be inconsistent with large N ...

Search for solar axions with mass around 1 eV using coherent conversion of axions into photons
Abstract A search for solar axions has been performed using an axion helioscope which is equipped with a 2.3-m long 4 T superconducting magnet, a gas container to hold dispersion-matching gas, PIN-photodiode X-ray detectors, and a telescope mount...
