Top quark production from black holes at the CERN LHC
Abstract LHC is expected to be a top quark factory. If the fundamental Planck scale is near a TeV, then we also expect the top quarks to be produced from black holes via Hawking radiation. In this Letter we calculate the cross sections for top quark ...

Decaying superheavy dark matter and subgalactic structure of the Universe
Abstract The collisionless cold dark matter (CCDM) model predicts overly dense cores in dark matter halos and overly abundant subhalos. We show that the idea that CDM are decaying superheavy particles which produce ultra-high energy cosmic rays with ...

Eight fermion terms in the effective action of the ABJM model
Abstract We study eight fermion terms in the effective action of the ABJM model. We show the non-renormalization of v 2 ...

D-term inflation in D-brane cosmology
Abstract We consider hybrid inflation in the braneworld scenario. In particular, we consider inflation in global supersymmetry with the D-terms in the scalar potential for the inflaton field to be the dominant ones (D-term inflation). We find that...

On the scaling rules for the anomaly-induced effective action of metric and electromagnetic field
Abstract The anomaly-induced effective action is a useful tool for deriving the contributions coming from quantum effects of massless conformal fields. It is well known that such corrections in the higher derivative vacuum sector of the...

Symmetric calorons
Abstract Calorons (periodic instantons) interpolate between monopoles and instantons, and their holonomy gives approximate Skyrmion configurations. We show that, for each caloron charge N⩽4, there exists a one-parameter family of calorons which are...

A low energy neutrino factory with non-magnetic detectors
Abstract We show that a very precise neutrino/anti-neutrino event separation is not mandatory to cover the physics program of a low energy neutrino factory and thus non-magnetized detectors like water Cerenkov or liquid Argon detectors can be used....

Prediction and possible observation of an oblate shape isomer in 190W
Abstract Energy-surface calculations for nuclides in the neutron-rich 190 74W116 region show consistently that the collective rotation of a deformed oblate shape is an energetically favoured mode, especially for angular momenta ...

Coherent states of the deformed Heisenberg–Weyl algebra in non-commutative space
Abstract In two-dimensional space a subtle point that for the case of both space–space and momentum–momentum non-commuting, different from the case of only space–space non-commuting, the deformed Heisenberg–Weyl algebra in non-commutative space is...

Some properties of a new class of plane symmetric solution
Abstract A new class of static plane symmetric solution of Einstein field equation, which is judged as the source of Taub solution, was presented in our previous work. In this Letter the properties of geodesics of this solution are explored. It is...

Phantom inflation and the “Big Trip”
Abstract Primordial inflation is regarded to be driven by a phantom field which is here implemented as a scalar field satisfying an equation of state p = ω ...

Effects of a phase transition on HBT correlations in an integrated Boltzmann+hydrodynamics approach
Abstract A systematic study of HBT radii of pions, produced in heavy ion collisions in the intermediate energy regime (SPS), from an integrated ( 3 + 1 )d...

Freedom in electroweak symmetry breaking and mass matrix of fermions in dimensional deconstruction model
Abstract There exists a freedom in a class of four-dimensional electroweak theories proposed by Arkani-Hamed et al. relying on deconstruction and Coleman–Weinberg mechanism. The freedom comes from the winding modes of the link variable (Wilson...

Liquid bridges and black strings in higher dimensions
Abstract Analyzing a capillary minimizing problem for a higher-dimensional extended fluid, we find that there exist startling similarities between the black hole-black string system (the Gregory–Laflamme instability) and the liquid drop-liquid...

Sensitivity to the standard model Higgs boson in exclusive double diffraction
Abstract We use a Monte Carlo implementation of recently developed models of double diffraction to assess the sensitivity of the LHC experiments to standard model Higgs bosons produced in exclusive double diffraction. The signal is difficult to...

Varying alpha and the electroweak model
Abstract Inspired by recent claims for a varying fine structure constant, alpha, we investigate the effect of “promoting coupling constants to variables” upon various parameters of the standard model. We first consider a toy model: Proca theory of...

The like-sign dimuon charge asymmetry in SUSY models
Abstract We study the new physics (NP) implications of the recently reported 3.2σ Standard Model (SM) deviation in the like-sign dimuon asymmetry at the Tevatron. Assuming that new physics only enters the ...
