The Degrees of Freedom in Hot Quenched QCD
Sourendu Gupta
Abstract
In quenched QCD, on lattices with =4, the absence of a pole in the pseudoscalar meson channel for T>Tc is demonstrated. A set of effective 4-fermi couplings is extracted. It is observed that this coupling is small in the vector channel for all T>Tc, but not in the pseudoscalar channel. The temperature dependence of hadronic parameters below is found to be small. NOTE: Latex source, no figures, needs espcrc2.sty from hep-lat macros.
