Non-perturbative renormalization of left-left four-fermion operators in quenched lattice QCD

M. Guagnelli, J. Heitger, C. Pena +2

We define a family of Schroedinger Functional renormalization schemes for the four-quark multiplicatively renormalizable operators of the $\Delta F=1$ and $\Delta F=2$ effective weak Hamil…
