Finite-temperature phase structure of lattice QCD with Wilson quark action.

The long-standing issue of the nature of the critical line of lattice QCD with the Wilson quark action at finite-temperatures, defined to be the line of vanishing pion screening mass, and its relation to the line of finite-temperature chiral transition is examined. Analytical and numerical evidence are presented that the critical line forms a cusp at a finite gauge coupling, and that the line o...

Non-perturbative determination of quark masses in quenched lattice QCD with the Kogut-Susskind fermion action

We report results of quark masses in quenched lattice QCD with the KogutSusskind fermion action, employing the Reguralization Independent scheme (RI) of Martinelli et al. to non-perturbatively evaluate the renormalization factor relating the bare quark mass on the lattice to that in the continuum. Calculations are carried out at β = 6.0, 6.2, and 6.4, from which we find m ud (2GeV) = 4.23(29)Me...
