Large-N reduction of SU(N) Yang-Mills theory with massive adjoint overlap fermions
Large-N reduction SU(N) Yang-Mills theory
2011/1/6
We study four dimensional large-N SU(N) Yang-Mills theory coupled to adjoint overlap fermions on a single site lattice. Lattice simulations along with perturbation theory show that the bare quark mass...
The Sphaleron Rate at the Electroweak Crossover
The Sphaleron Rate the Electroweak Crossover
2011/1/6
The baryon number is violated in the Standard Model by non-perturbative sphaleron transitions. At temperatures above the electroweak scale, the rate of the sphaleron transitions is unsuppressed and ha...

Background independent condensed matter models for quantum gravity
Background independent condensed matter models quantum gravity
2010/12/27
A number of recent proposals for a quantum theory of gravity are based on the idea that spacetime geometry and gravity are derivative concepts and only apply at an approximate level. There are two fu...
The Boundary Multiplet of N=4 SU(2)xU(1) Gauged Supergravity on Asymptotically-AdS_5
The Boundary Multiplet Gauged Supergravity
2010/12/23
We consider N=4 SU(2)xU(1) gauged supergravity on asymptotically-AdS_5 backgrounds. By a near-boundary analysis we determine the boundary-dominant components of the bulk fields from their partially g...

2011/1/6
We present a perturbative calculation of the improvement coefficients of SU(2) gauge theory with adjoint representation Wilson-clover fermions and using Schrodinger functional boundary conditions. The...

Possible splitting of deconfinement and chiral transitions in strong magnetic fields in QCD
chiral transitions strong magnetic fields in QCD
2010/12/27
We show that finite-temperature deconfinement and chiral transitions can split in a strong enough magnetic field. The splitting in critical temperatures of these transitions in a constant magnetic fie...

Nucleon strange quark content two-flavor lattice QCD
2011/1/6
Strange quark content of the nucleon is calculated in dynamical lattice QCD employing the overlap fermion formulation. For this quantity, exact chiral symmetry guaranteed by the Ginsparg-Wilson relati...

Strange quark content of the nucleon is calculated in dynamical lattice QCD employing the overlap fermion formulation. For this quantity, exact chiral symmetry guaranteed by the Ginsparg-Wilson relati...
On the one hand, inflation is an extremely convincing scenario: it solves most cosmological paradoxes and generates fluctuations that became the seeds for the growth of structures. It, however, suffer...
We present the results of the recent high precision lattice calculation of the average up/down, strange and charm quark masses performed by ETMC with Nf=2 twisted mass Wilson fermions. The analysis in...

Four-dimensional Yang-Mills theory three-dimensional fermion membrane
2010/12/27
We study the four-dimensional Yang-Mills theory in the presence of a three-dimensional membrane of fermions by lattice Monte Carlo simulations. We analyze the phase structure of this theory at finite...
Particle with non-Abelian charge: classical and quantum
non-Abelian charge classical quantum
2010/12/23
We construct an action in the worldline formalism for a non-Abelian charged particle in a non-Abelian background field, described by real bosonic variables, leading to a set of the well known classica...
