内容記述 | We calculate one-loop renormalization factors of bilinear quark operators for the gluon action including six-link loops and an O(a)-improved quark action in the limit of a massless quark. We find that finite parts of the one-loop coefficients of renormalization factors diminish monotonically as either of the coefficients c1 or c2+c3 of the six-link terms is decreased below zero. Detailed numerical results are given, for general values of the clover coefficient, for the tree-level improved gluon action in the Symanzik approach (c1=-1/12,c2=c3=0) and for the choices suggested by Wilson (c1=-0.252,c2=0,c3=-0.17) and by Iwasaki (c1=-0.331,c2=c3=0 and c1=-0.27,c2+c3=-0.04) from renormalization-group alyses. Compared with the case of the standard plaquette gluon action, the finite parts of the one-loop coefficients are reduced by 10-20 % for the Symanzik action, and approximately by a factor of 2 for the renormalization-group improved gluon actions. | |||||
