Spectral properties of quarks above the critical temperature for
deconfinement are analyzed in quenched lattice QCD on lattices of
size $128^3\times16$.
We study quark spectral function in energy and momentum space,
focusing on the values of the thermal mass and the dispersion
relations of normal and plasmino modes at nonzero momentum, as well
as their spatial volume dependence. Our...

It has long been known that QCD undergoes a deconfining phase
transition at high temperature. One of the consequent features of this
new, quark-gluon phase is that hadrons become unbounded. In this talk
meson correlation functions at non-zero momentum are studied in
the deconfined phase using the Maximum Entropy Method. In particular,
both the longitudinal and transverse vector...

We investigate medium effects on mesonic screening lengths for QCD with
2-flavours of dynamical staggered quarks on lattices with cutoff a=1/6T.
In our study, T ranges from 0.89 Tc to 1.92 Tc, spanning both the hadronic
and the quark-gluon plasma phases. While chiral symmetry restoration in the
vector channel appears to take place near Tc, it is seen in the scalar channel
only above...

The quark-gluon plasma produced in heavy ion collisions at RHIC energy is known to be very close to the ideal fluid. Calculations with viscosities and other transport coefficients, i.e. second order dissipative hydrodynamics is known as a causal theory, it includes many phenomenological transport coefficients. We attempt to constrain those transport coefficients by SU(3) lattice gauge...

Strong coupling lattice QCD (SC-LQCD) is a useful approach to study dense matter based on QCD. With the aid of the mean field for the chiral condensate and 1/d expansion, phase diagram has been obtained in the strong coupling limit and with the NLO / NNLO finite coupling effects. Recently, de Forcrand and Fromm investigated the phase diagram in the Monomer-Dimer-Polymer (MDP) algorithm in the...
