Description

We present preliminary results for the non-perturbative renormalization of the tensor current in QCD for $N_f=0,2$, as well as an ongoing extension to $N_f=2+1$. The renormalization group running is computed in the continuum limit for a wide range of scales, using various Schrodinger Functional (SF) schemes and finite volume recursive techniques. In all these schemes, we have also computed the matching factor to MSbar and RI-MOM, which allows for a NLO matching to the RGI operator at high energies. An example application of the results is the renormalization and matching of the tensor currents entering the effective Hamiltonian for $b \to s$ transitions.
