| We determine the quark masses and the chiral condensate in the <(MS)over bar> scheme at NNLO from Lattice QCD in the quenched approximation at beta = 6.0, beta = 6.2 and beta = 6.4 using both the Wilson and the tree-level improved SW-Clover fermion action. We extract these quantities using the Vector and the Axial Ward Identities and nonperturbative value of the renormalization constants. We compare the results obtained vr th the two methods and we study the O(a) dependence of the quark masses for both actions. | |||
