Heavy Quark Free Energies and Screening in SU(2) Gauge Theory
S. Digal, S. Fortunato, P. Petreczky
We investigate the singlet, triplet and colour average heavy quark free energies in SU(2) pure gauge theory at various temperatures T. We focus on the long distance behaviour of th…
Hadron correlators, spectral functions and thermal dilepton rates from lattice QCD
F. Karsch, S. Datta, E. Laermann +3
We discuss information on thermal modifications of hadron properties which can be extracted from the structure of Euclidean correlation functions of hadronic currents as well as mo…
A Study of Charmonium Systems across the Deconfinement Transition
Saumen Datta, Frithjof Karsch, Peter Petreczky +1
We present results from lattice studies of charmonium systems near the deconfinement transition temperature. On quenched isotropic lattices with lattice spacings between 0.02 and 0…
Heavy Quark Anti-Quark Free Energy and the Renormalized Polyakov Loop
O. Kaczmarek, F. Karsch, P. Petreczky +1
We calculate the colour averaged and colour singlet free energies of static quark anti-quark sources placed in a thermal gluonic heat bath. We discuss the renormalization of these…
Parton Percolation and J/Psi Suppression
S. Digal, S. Fortunato, P. Petreczky +1
The geometric clustering of partons in the transverse plane of nuclear collisions leads for increasing A or sqrt(s) to percolation. In the resulting condensate, the partons are dec…
