Analysis of the $N_f=2+1$ lattice QCD results on the lowest-lying baryon masses using covariant ChPT
$N_f=2+1$ lattice QCD results lowest-lying baryon masses covariant ChPT

We review recent progress in the understanding of low-energy baryon structure by means of chiral perturbation theory.

Finite-volume lattice QCD calculations o er the possibility of extracting resonance parameters
from the energy-dependent elastic phase-shift computed using the Luscher technique. In this letter,as a...
Comparison of the mass preconditioned HMC and the DD-HMC algorithm for two-flavour QCD
Comparison mass preconditioned HMC DD-HMC algorithm two-flavour QCD
2011/1/13
Mass preconditioned HMC and DD-HMC are among the most popular algorithms to simulate Wilson fermions. We present a comparison of the performance of the two algorithms for realistic
quark masses and l...

Possible splitting of deconfinement chiral transitions strong magnetic fields
2011/1/14
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...

Flavor structure baryon-baryon interaction lattice QCD
2011/1/7
We investigate baryon-baryon (BB) interactions in the 3-flavor full QCD simulations with degenerate quark masses for all flavors. The BB potentials in the orbital S-wave are extracted from the Nambu-B...

Three Nucleon Force full QCD Lattice calculations
2011/1/13
We study the three nucleon force in the triton channel using dynamical clover fermion lattice
QCD. The Nambu-Bethe-Salpeter wave function is utilized to obtain the potentials among three
nucleons.

2011/1/14
We present a sum-rule extraction of the decay constants of heavy-lightmesons from the two-point
correlator of pseudoscalar currents [1]. To this end, we compare the perturbative expansions for the co...

We present a sum-rule extraction of decay constants of heavy mesons from the two-point correlator of heavy-light pseudoscalar currents. Our primary concern is to control the uncertainties of the decay...
Absence of sign problem in the (saddle point approximation of the) nilpotency expansion of QCD at finite chemical potential

We have developed a method to derive the (approximate) quark contribution to the fermion free
energy of QCD on a lattice, at finite temperature and chemical potential, with Kogut-Susskind

Electromagnetically superconducting phase of QCD vacuum induced by strong magnetic field
Quantum Chromodynamics Strong Magnetic Fields Superconductivity Rho Condensation
2011/1/14
In this talk we discuss our recent suggestion that the QCD vacuum in a sufficiently strong magnetic field (stronger than 1016 Tesla) may undergo a spontaneous transition to an electromagnetically supe...
Recent developments on the determination of the spin-1/2 spectrum of the nucleon in full QCD
are presented. Our focus is on the PACS-CS 2+1 flavor configurationsmade available through the
ILDG.

2011/1/7
I report the results of a series of works on the phase diagram of theories with a different number of colors and/or quarks in a different representation than in QCD. Similarities as well as difference...
