Light Hadron Spectrum, Renormalization Constants and Light Quark Masses with Two Dynamical Fermions☆

The results of a preliminary partially quenched ( N f = 2 ) study of the light hadron spectrum, renormalization constants and light quark masses are presented. Numerical simulations are carried out with the LL-SSOR preconditioned Hybrid Monte Carlo with two degenerate dynamical fermions, using the plaquette gauge action and the Wilson quark action at β = 5.8 . Finite volume effects have been investigated employing two lattice volumes: 16 3 × 48 and 24 3 × 48. Configurations have been generated at four values of the sea quark mass corresponding to M P S / M V ≃ 0.6 ÷ 0.8 .
