Spectral properties quarks above Tc -- thermal mass
2011/1/6
Spectral properties of quarks above the critical temperature for deconfinement are analyzed in quenched lattice QCD on lattices of size 128^3x16. We study quark spectral function in energy and momentu...

Spectral properties quarks above Tc -- thermal mass
2011/1/6
Spectral properties of quarks above the critical temperature for deconfinement are analyzed in quenched lattice QCD on lattices of size 128^3x16. We study quark spectral function in energy and momentu...
We propose a warm inflationary model in the context of relativistic D-brane inflation in a warped throat. The inflaton has Dirac-Born-Infeld (DBI) kinetic term and is coupled to radiation through a di...
UV and IR Zeros of Gauge Theories at The Four Loop Order and Beyond
UV IR Zeros Gauge Theories
2010/12/27
We unveil the general features of the phase diagram for any gauge theory with fermions transforming according to distinct representations of the underlying gauge group, at the four-loop order. We cla...
Hawking-like radiation from evolving black holes and compact horizonless objects
Hawking-like radiation evolving black holes compact horizonless objects
2010/12/27
Usually, Hawking radiation is derived assuming (i) that a future eternal event horizon forms, and (ii) that the subsequent exterior geometry is static. However, one may be interested in either conside...
On messengers and metastability in gauge mediation
messengers metastability gauge mediation
2010/12/23
One notoriously difficult problem in perturbative gauge mediation of supersymmetry breaking via messenger fields is the generic presence of a phenomenologically unacceptable vacuum with messenger vev...
Regge Field Theory in zero transverse dimensions: loops versus "net" diagrams
Regge Field Theory zero transverse dimensions
2010/12/23
Toy models of interacting Pomerons with triple and quaternary Pomeron vertices in zero transverse dimension are investigated. Numerical solutions for eigenvalues and eigenfunctions of the correspondin...
Mass matrices of twice four families of quarks and leptons, scalars and gauge fields as predicted by the ''spin-charge-family-theory''
Mass matrices scalars spin-charge-family-theory
2010/12/27
The theory unifying spin and charges and predicting families, proposed as a new way to explain the assumptions of the standard model of the electroweak and colour interactions, predicts at the low ene...
Mutated hybrid inflation in $f(R,{\Box}R)$-gravity
Mutated hybrid inflation High Energy Physics
2010/12/23
A new hybrid inflationary scenario in the context of $f(R,{\Box}R)$-gravity is proposed. Demanding the waterfall field to 'support the potential from below' [unlike the original proposal by Stewart i...
Dual DSR
Dual DSR High Energy Physics
2010/12/23
We develop the physics of dual kappa Poincare algebra, which we will call dual DSR. First, we show that the dual kappa Poincare algebra is isomorphic to de Sitter algebra and its spactime is essentia...
EOS in 2+1 flavor QCD with improved Wilson quarks by the fixed-scale approach
EOS 2+1 flavor QCD improved Wilson quarks
2011/1/6
We present the status of our study on the equation of state in 2+1 flavor QCD with non-perturbatively improved Wilson quarks coupled with the RG improved glue. We apply the T-integration method to non...

Inhomogeneous fluid flows which become supersonic are known to produce acoustic analogs of ergoregions and horizons. This leads to Hawking-like radiation of phonons with a temperature essentially give...
Ordinary matter is described by six fundamental parameters: three couplings (gravitational, electromagnetic and strong) and three masses: the electron's ($m_e$) and those of the up ($m_u$) and down ($...
