Frobenius transformation, mirror map and instanton numbers
Abstract We show that one can express Frobenius transformation on middle-dimensional p-adic cohomology of Calabi–Yau threefold in terms of mirror map and instanton numbers. We express the mirror map in terms of Frobenius transformation on p-adic...

Higgs production at the LHC in warped extra-dimensional models
Abstract The extra-dimensional model in which the bulk geometry is a slice of anti-de Sitter space is a particularly attractive extension of the Standard Model as it allows to address the gauge hierarchy problem, as well as the mass hierarchy...

Prospects of inflation with perturbed throat geometry
Abstract We study brane inflation in a warped deformed conifold background that includes general possible corrections to the throat geometry sourced by coupling to the bulk of a compact Calabi–Yau space. We focus specifically, on the perturbation by ...

On the discretization of physical momenta in lattice QCD
Abstract The adoption of two distinct boundary conditions for two fermions species on a finite lattice allows to deal with arbitrary relative momentum between the two particle species, in spite of the momentum quantization rule due to a limited...

The unified first law in “cosmic triad” vector field scenario
Abstract In this Letter, we try to apply the unified first law to the “cosmic triad” vector field scenario both in the minimal coupling case and in the non-minimal coupling case. After transferring the non-minimally coupling action in the Jordan...

The exact decomposition of gauge variables in lattice Yang–Mills theory
Abstract In this Letter, we consider lattice versions of the decomposition of the Yang–Mills field a la Cho–Faddeev–Niemi, which was extended by Kondo, Shinohara and Murakami in the continuum formulation. For the SU ...

Model-independent analysis of tri-bimaximal mixing: A softly-broken hidden or an accidental symmetry?
Abstract To address the issue of whether tri-bimaximal mixing (TBM) is a softly-broken hidden or an accidental symmetry, we adopt a model-independent analysis in which we perturb a neutrino mass matrix leading to TBM in the most general way but...

Magnetic moment of hyperons in nuclear matter by using quark–meson coupling models
Abstract We calculate the magnetic moments of hyperons in dense nuclear matter by using relativistic quark models. Hyperons are treated as MIT bags, and the interactions are considered to be mediated by the exchange of scalar and vector mesons which ...

Brane solution with an increasing warp factor
Abstract We present a new brane solution in the ( 1 + 5 )-dimensional space–time with an increasing warp factor, which localizes the zero modes of all kinds ...

Supersymmetric dark matter search via spin-dependent interaction with 3He
Abstract The potentialities of MIMAC-He3, a MIcro-tpc MAtrix of Chambers of Helium-3, for supersymmetric dark matter search are discussed within the framework of effective MSSM models without gaugino mass unification at the GUT scale. A...

Comment on “Strong coupling in extended Hořava–Lifshitz gravity” [Phys. Lett. B 685 (2010) 197]
Abstract We show that, contrary to the claim made in arXiv:0911.1299, the extended Hořava gravity model proposed in arXiv:0909.3525 does not suffer from a strong coupling problem. By studying the observational constraints on the model we determine...

Coulomb interaction from the interplay between confinement and screening
Abstract It has been noticed that confinement effects can be described by the addition of a −Fμν aFaμν ...

The generalized second law in irreversible thermodynamics for the interacting dark energy in a non-flat FRW universe enclosed by the apparent horizon
Abstract We investigate the validity of the generalized second law in irreversible thermodynamics in a non-flat FRW universe containing the interacting dark energy with cold dark matter. The boundary of the universe is assumed to be enclosed by the...

Nonequivalent Seiberg–Witten maps for noncommutative massive U(N) gauge theory
Abstract Massive vector fields can be described in a gauge invariant way with the introduction of compensating fields. In the unitary gauge one recovers the original formulation. Although this gauging mechanism can be extended to noncommutative...

Discreteness and the origin of probability in quantum mechanics
Abstract Attempts to derive the Born rule, either in the Many Worlds or Copenhagen interpretation, are unsatisfactory for systems with only a finite number of degrees of freedom. In the case of Many Worlds this is a serious problem, since its goal...

Two-loop static QCD potential for general colour state
Abstract In this Letter, we extend the known results for the QCD potential between a static quark and its antiquark by computing the two-loop corrections to the colour-octet state.

Chiral extrapolation and determination of low-energy constants from lattice data

Stochastic quantization and the role of time in quantum gravity
Abstract We show that the noncritical string field theory developed from two-dimensional quantum gravity in the framework of causal dynamical triangulations can be viewed as arising through a stochastic quantization. This requires that the proper...

Observations on the Wilson fermions in the ϵ regime
Abstract We make several observations concerning the low quark mass region with Wilson fermions and how this is connected with the ϵ regime in the continuum. A transition from tiny cutoff effects to rather large discretization errors would take...

Two component charged condensate in white dwarfs
Abstract The possibility of the formation of a condensate of charged spin-0 nuclei inside white dwarf cores, studied in [G. Gabadadze, R.A. Rosen, JCAP 0810 (2008) 030, arXiv:0806.3692] and [G. Gabadadze, D. Pirtskhalava, JCAP 0905 (2009) 017,...
