Behavior of Charmonium Systems after Deconfinement
Saumen Datta, Frithjof Karsch, Peter Petreczky +1
We present a study of charmonia in hot gluonic plasma, for temperatures upto three times the deconfinement transition temperature Tc. q \bar{q} systems with quark masses close to t…
Hard probes in heavy ion collisions at the LHC: heavy flavour physics
M. Bedjidian, D. Blaschke, G. T. Bodwin +26
We present the results from the heavy quarks and quarkonia working group. This report gives benchmark heavy quark and quarkonium cross sections for and collisions at the…
Photon Physics in Heavy Ion Collisions at the LHC
F. Arleo, P. Aurenche, F. Bopp +32
Various pion and photon production mechanisms in high-energy nuclear collisions at RHIC and LHC are discussed. Comparison with RHIC data is done whenever possible. The prospect of…
Quarkonium at finite temperature
P. Petreczky
I discuss quarkonium spectral functions at finite temperature reconstructed using the Maximum Entropy Method. I show in particular that the J/psi survives in the deconfined phase u…
Free Meson Spectral Functions on the Lattice
S. Stickan, F. Karsch, E. Laermann +1
We present results from an analytic calculation of thermal meson spectral functions in the infinite temperature (free field) limit. We compare spectral functions for various lattic…
Heavy quark free energies, potentials and the renormalized Polyakov loop
O. Kaczmarek, F. Karsch, P. Petreczky +1
We discuss the renormalized free energy of a heavy quark anti-quark pair in the color singlet channel for quenched and full QCD at finite temperature. The temperature and mass depe…
Charmonium at finite temperature
P. Petreczky, S. Datta, F. Karsch +1
We study charmoinum correlators and spectral functions at finite temperature within the quenched approximation using isotropic lattices with lattice spacing a^-1=4.86 GeV and 9.72…
Lattice calculations of meson correlators and spectral functions at finite temperature
Peter Petreczky
I review recent progress in relating meson spectral function to imaginary time correlation function at finite temperature calculated on isotropic as well as on anisotropic lattices…
Heavy Quark Free Energies and Screening in SU(2) Gauge Theory
S. Digal, S. Fortunato, P. Petreczky
We study the properties of the free energy of infinitely heavy quark anti-quark pair in SU(2) gauge theory. By means of lattice Monte Carlo simulations we calculated the free energ…
Infinite temperature limit of meson spectral functions calculated on the lattice
F. Karsch, E. Laermann, P. Petreczky +1
We analyze the cut-off dependence of mesonic spectral functions calculated at finite temperature on Euclidean lattices with finite temporal extent. In the infinite temperature limi…
Renormalized quark-anti-quark free energy
F. Zantow, O. Kaczmarek, F. Karsch +1
We present results on the renormalized quark-anti-quark free energy in SU(3) gauge theory at finite temperatures. We discuss results for the singlet, octet and colour averaged free…
