Description
We explore various non-perturbative renormalisation schemes in the framework of the Rome-Southampton method. In particular, we implement several non-exceptional interpolating momentum schemes, where the momentum transfer is not restricted to the symmetric point defined in RI/SMOM. Using flavour non-singlet quark bilinears, we compute the renormalisation factors of the quark mass and wave function for Nf = 3 flavours of dynamical quarks. We investigate the perturbative and non-perturbative scale-dependence and give the corresponding one-loop matching factorto MS. Our numerical results are obtained from lattice simulations performed with Domain Wall fermions based on ensembles generated by RBC-UKQCD collaborations.
