Abstract: (Elsevier)

We determine the renormalization constants of two-quark operators for the clover action on the lattice, using chiral Ward identities. These renormalization constants are required for the determination of physical quantities, such as f π , f ϱ −1 and the quark masses from lattice calculations. Our results show that at β =6.0, with a sample of eighteen gauge configurations, it is possible to determine the renormalization constants with an error of a few percent.
