Abstract:

We report on a lattice investigation of improved quenched Wilson fermions above and below the confinement-deconfinement phase transition. Results on meson screening masses as well as spatial wave functions are presented. Moreover, the meson dispersion relation is studied. Below the critical temperature we do not observe any significant temperature effect while above

T_c

the data are consistent with a leading free quark behavior.

lattice field theory
gauge field theory: SU(3)
approximation: quenching
critical phenomena: confinement
pseudoscalar meson: mass spectrum
