Non-perturbative renormalization of the $\Delta$S=2 operator and the heavy-light axial current
We apply a recently introduced non-perturbative renormalization method to two types of lattice operators: the \Delta S=2 four fermion operator and the heavy-light static axial current, which are relevant for the physics of K and B mesons respectively. The results of the non-perturbative calculations...

| Sumario: | We apply a recently introduced non-perturbative renormalization method to two types of lattice operators: the \Delta S=2 four fermion operator and the heavy-light static axial current, which are relevant for the physics of K and B mesons respectively. The results of the non-perturbative calculations of the renormalization constants are compared with the corresponding perturbative ones. |
