摘要：

We discuss the improvement of local four-fermion operators and we present the one-loop perturbative calculation of their renormalization constants and mixing coefficients in the theory defined by a nearest-neighbour improved lattice action. This calculation is a necessary ingredient for improved Monte Carlo computations of hadronic matrix elements relevant for weak interactions.
