Classical and quantum initial conditions for Higgs inflation
Abstract We investigate whether Higgs inflation can occur in the Standard Model starting from natural initial conditions or not. The Higgs has a non-minimal coupling to the Ricci scalar. We confine our attention to the regime where quantum Einstein...

QCD θ-vacua from the chiral limit to the quenched limit
Abstract We investigate the dependence of the QCD vacuum structure on the θ-angle and quark mass, using the Di-Vecchia–Veneziano model. Although the Di-Vecchia–Veneziano model is a chiral effective model, it contains the topological properties of...

A Study of Neutronics Effects of the Spacer Grids in a Typical PWR via Monte Carlo Calculation
Abstract Spacer grids play an important role in maintaining the proper form of the fuel assembly structure and ensuring the safety of reactor core design. This study applies the Monte Carlo method to the analysis of the neutronics effects of spacer...

Cosmology from quantum potential in brane–anti-brane system
Abstract Recently, some authors removed the big-bang singularity and predicted an infinite age of our universe. In this paper, we show that the same result can be obtained in string theory and M-theory; however, the shape of universe changes in...

The emission of Gamma Ray Bursts as a test-bed for modified gravity
Abstract The extreme physical conditions of Gamma Ray Bursts can constitute a useful observational laboratory to test theories of gravity where very high curvature regimes are involved. Here we propose a sort of curvature engine capable, in...

S-functions, spectral functions of hyperbolic geometry, and vertex operators with applications to structure for Weyl and orthogonal group invariants
Abstract In this paper we analyze the quantum homological invariants (the Poincaré polynomials of the sl ...

Search for Spatial and Temporary Variations of Galactic Cosmic Ray Positrons in PAMELA Experiment
Abstract The PAMELA experiment is gathering data since 2006 on board the Resurs DK1 satellite (orbit with inclination 70.4°, the altitude 350-600km). The instrument consists magnetic spectrometer, silicon-tungsten imaging electromagnetic...

Dalitz plot analyses of charmless b-hadron decays at LHCb
Abstract Charmless b-hadron decays are suppressed in the Standard Model by tiny CKM matrix elements which brings the tree amplitudes to levels comparable with loop amplitudes, and potentially New Physics amplitudes. CP violation measurements using...

Electroweak penguins at LHCb
Abstract Electroweak penguin decays are flavour-changing neutral current processes, and are highly suppressed in the Standard Model. They can only proceed via loop diagrams. Such decays may receive contributions from New Physics and change their...

Charge and color breaking constraints in the Minimal Supersymmetric Standard Model associated with the bottom Yukawa coupling
Abstract Testing the stability of the electroweak vacuum in any extension of the Standard Model Higgs sector is of great importance to verify the consistency of the theory. Multi-scalar extensions as the Minimal Supersymmetric Standard Model...

Development of a Rapid Temperature Scanning System for Pulsed Magnetic Fields and its Applications
Abstract An apparatus, which scans temperature in sub-seconds for measuring the temperature dependence of the resistivity, is proposed. This apparatus contains a thermal bath and a sample platform on which a thin-film thermometer and a thin-film...

Anti-de-Sitter regular electric multipoles: Towards Einstein–Maxwell-AdS solitons
Abstract We discuss electrostatics in Anti-de-Sitter (AdS) spacetime, in global coordinates. We observe that the multipolar expansion has two crucial differences to that in Minkowski spacetime. First, there are everywhere regular solutions, with...

Exploring hints for dark energy density evolution in light of recent data
Abstract Considering a quadratic parameterization of the dark energy density, we explore signatures of evolution using data from gas mass fraction in clusters, type Ia supernova, BAO and CMB. We find – excluding CMB data – a preference for an...

An alternative interpretation for cosmic ray peaks
Abstract We propose an alternative mechanism based upon dark matter (DM) interpretation for anomalous peak signatures in cosmic ray measurements, assuming an extended dark sector with two DM species. This is contrasted with previous effort to...
