摘要
We impose the axial and vector Ward identities on local fermion bilinear operators in the Sheikholesalami-Wohlert discretization of fermions. From this we obtain all the coefficients needed to improve the theory at O(a), as well as the scale and scheme independent renormalization constants, Z_A, Z_V and Z_S/Z_P.
