Early spin determination at the LHC?
Abstract If signals of new physics are discovered at the LHC it will be crucial to determine the spin structure of the new model. We discuss a method that can help to address this question with a low integrated luminosity, L ...

Fermion tunnels of higher-dimensional anti-de Sitter Schwarzschild black hole and its corrected entropy
Abstract Applying the method beyond semiclassical approximation, fermion tunneling from higher-dimensional anti-de Sitter Schwarzschild black hole is researched. In our work, the “tortoise” coordinate transformation is introduced to simplify Dirac...

Effective actions of a Gauss–Bonnet brane world with brane curvature terms
Abstract We consider a warped brane world scenario with two branes, Gauss–Bonnet gravity in the bulk, and brane localised curvature terms. When matter is present on both branes, we investigate the linear equations of motion and distinguish three...

Discreteness of space from the generalized uncertainty principle
Abstract Various approaches to Quantum Gravity (such as String Theory and Doubly Special Relativity), as well as black hole physics predict a minimum measurable length, or a maximum observable momentum, and related modifications of the Heisenberg...

Dark energy, inflation and the cosmic coincidence problem
Abstract We show that holographic dark energy could explain why the current dark energy density is so small, if there was an inflation with a sufficient expansion in the early universe. It is also suggested that an inflation with the number of...

QCD plasma instabilities and isotropization
Abstract We solve the coupled Wong Yang–Mills equations for both U ( 1 ) and SU ( ...

Extra dimensions, warped compactifications and cosmic acceleration
Abstract We report on explicit cosmological solutions within the framework of an inflating de Sitter brane embedded in five- and ten-dimensional bulk spacetimes. In the specific example we study the brane tension is induced by the curvature related...

Spontaneous rotational symmetry breaking and roton like excitations in gauged σ-model at finite density
Abstract The linear σ-model with a chemical potential for hypercharge is a toy model for the description of the dynamics of the kaon condensate in high density QCD. We analyze the dynamics of the gauged version of this model. It is shown that...

Holography at string field theory level: Conformal three point functions of BMN operators
Abstract We propose a general framework for applying the pp-wave approximation to holographic calculation in the AdS/CFT correspondence. By assuming the existence and some properties of string field theory (SFT) on the ...

Heavy quark jet tomography of Pb+Pb at LHC: AdS/CFT drag or pQCD energy loss?

BRST Lagrangian construction for spin-2 field in Einstein space
Abstract We explore a new possibility of BRST construction in higher spin field theory to obtain a consistent Lagrangian for massive spin-2 field in Einstein space. Such approach automatically leads to gauge invariant Lagrangian with suitable...

Meson widths from string worldsheet instantons
Abstract We show that open strings living on a D-brane which lies outside an AdS black hole can tunnel into the black hole through worldsheet instantons. These instantons have a simple interpretation in terms of thermal quarks in the dual Yang–Mills ...

Solving the neutrino parameter degeneracy by measuring the T2K off-axis beam in Korea
Abstract The T2K neutrino oscillation experiment will start in 2009. In this experiment the center of the neutrino beam from J-PARC at Tokai village will go through underground beneath Super-Kamiokande, reach the sea level east of Korean shore, and...

On the conformally coupled scalar field quantum cosmology
Abstract We propose a new initial condition for the homogeneous and isotropic quantum cosmology, where the source of the gravitational field is a conformally coupled scalar field, and the maximally symmetric hypersurfaces have positive curvature....

Tests of a family gauge symmetry model at 103 TeV scale
Abstract Based on a specific model with U(3) family gauge symmetry at 103 TeV scale, we show its experimental signatures to search for. Since the gauge symmetry is introduced with a special purpose, its gauge coupling constant and gauge boson mass...
