      Singlet versus nonsinglet perturbative renormalization of fermion bilinears 

      Constantinou, Martha G.; Hadjiantonis, Marios; Panagopoulos, Haralambos G.; Spanoudes, Gregoris (2016)
      In this paper, we present the perturbative evaluation of the difference between the renormalization functions of flavor singlet and nonsinglet bilinear quark operators on the lattice. The computation is performed to two ...
