Detecting Higgs bosons with muons at hadron colliders
Abstract We investigate the prospects for the discovery of neutral Higgs bosons with a pair of muons by direct searches at the CERN large hadron collider (LHC) as well as by indirect searches in the rare decay ...

Classical kinematics for Lorentz violation
Abstract Classical point-particle relativistic lagrangians are constructed that generate the momentum–velocity and dispersion relations for quantum wave packets in Lorentz-violating effective field theory.

A Skyrme-type proposal for baryonic matter
Abstract The Skyrme model is a low-energy effective field theory for QCD, where the baryons emerge as soliton solutions. It is, however, not so easy within the standard Skyrme model to reproduce the almost exact linear growth of the nuclear masses...

Neutrino dark energy and baryon asymmetry from Higgs sector
Abstract We propose a new model to explain the neutrino masses, the dark energy and the baryon asymmetry altogether. In this model, neutrinos naturally acquire small Majorana masses via type-II seesaw mechanism, while the pseudo-Nambu–Goldstone...

Possible capture of keV sterile neutrino dark matter on radioactive β-decaying nuclei
Abstract There exists an observed “desert” spanning six orders of magnitude between O ( 0.5 ) eV and ...

Selectivity of the nucleon-induced deuteron breakup and relativistic effects
Abstract Theoretical predictions for the nucleon-induced deuteron breakup process based on solutions of the three-nucleon Faddeev equation including such relativistic features as the relativistic kinematics and boost effects are presented. Large...

Transverse momentum in semi-inclusive deep inelastic scattering
Abstract Within the framework of perturbative quantum chromodynamics we derive the evolution equations for transverse momentum dependent distributions and apply them to the case of semi-inclusive deep inelastic scattering. The evolution equations...

Some notes on the big trip
Abstract The big trip is a cosmological process thought to occur in the future by which the entire universe would be engulfed inside a gigantic wormhole and might travel through it along space and time. In this Letter we discuss different arguments...

Dark matter as a guide toward a light gluino at the LHC
Abstract Motivated by specific connections to dark matter signatures, we study the prospects of observing the presence of a relatively light gluino whose mass is in the range ∼ ( ...

Ruppeiner geometry and 2D dilaton gravity in the thermodynamics of black holes
Abstract We study the geometric approach to the black hole thermodynamics. The geometric description of the equilibrium thermodynamics comes from Ruppeiner geometry based on a metric on the thermodynamic state space. For this purpose, we consider...

Proposal of a simple method to estimate neutrino oscillation probability and CP violation in matter
Abstract We study neutrino oscillation within the framework of three generations in matter. We propose a simple method to approximate the coefficients A,B and C which do not depend on the CP phase δ in the oscillation probability P(ν ...

On the hidden charm state at 3872 MeV
Abstract We discuss some puzzling aspects of the narrow hidden charm resonance that was recently discovered by the Belle Collaboration at mass 3872 MeV. In order to determine its quantum numbers, a crucial piece of information is the spin of the...

More about chiral symmetry restoration at finite temperature in the planar limit
Abstract In the planar limit, in the deconfined phase, the Euclidean Dirac operator has a spectral gap around zero. We show that functions of eigenvalues close to the spectral edge, which are independent of common rescalings and shifts gauge...

Unitarity constraints on neutral pion electroproduction

Colour strings vs. hard pomeron in perturbative QCD
Abstract Average multiplicities and transverse momenta in AA collisons at high energies are studied in the soft and hard regions, in fusing string and perturbative QCD scenarios, respectively. Striking similarities are found between the predictions...

Quantum dynamics of massive particles in a non-commutative two-sheeted space–time
Abstract We study a formal extension of the Dirac equation in the framework of a non-commutative two-sheeted space–time. It is shown that this approach naturally extends the classical Dirac theory by doubling the number of fermionic states, which...

The big bounce in rainbow universe
Abstract The usual Einstein's equations is modified as a one parameter family of equations in the framework of rainbow gravity. In this Letter we derive the modified Friedmann–Robertson–Walker (FRW) equations when the cosmological evolution of...

Graviton excitations and Lorentz–Violating gravity with cosmological constant
Abstract Motivated by the interest raised by the problem of Lorenz-symmetry violating gauge theories in connection with gravity models, this contribution sets out to provide a general method to systematically study the excitation spectrum of gravity ...

The generalized second law in phantom dominated universes in the presence of black holes
Abstract This Letter considers the generalized second law of gravitational thermodynamics in two scenarios featuring a phantom dominated expansion plus a black hole. The law is violated in both scenarios.
