摘要: We briefly review and compare three methods (one perturbative, one based on Ward Identities nonperturbative) for the calculation of renormalization constants lattice operators. The following results are presented: (a) non perturbative operators with light quarks; (b) a heavy (charm) quark mass its KLM improvement; (c) determination mixing ΔS = 2 operator.
