abstract
Non-perturbative renormalization factors of bilinear quark operators are computed for the Chirally Improved lattice action with two dynamic quarks. The analysis is based on five different parameter sets with lattice size 12^3 x 24 and four parameter sets with lattice size 16^3 x 32. For the pseudoscalar renormalization factor the pion pole contribution is subtracted and chiral extrapolations are performed. Results are given in RIprime- and MSbar-scheme as well as in RGI-form.

Renormalising vector currents in lattice QCD using momentum-subtraction schemes
Z_V for HISQ vector currents is exact and condensate-free in RI-SMOM and in a modified ratio scheme, but the standard RI'-MOM scheme has O(1%) condensate contamination.
