Abstract

We present preliminary results of the non-perturbative renormalization group (RG) running of the flavor non-singlet tensor operator. We employ the χSF scheme for N_f=3 QCD using ensembles generated by the ALPHA collaboration for the computation of the quark mass running. The χSF property of automatic O(a) improvement prevents the O(a) mixing of the correlation functions.
