摘要：

The conservation of the isovector axial current in lattice QCD with massless Wilson quarks is studied to one-loop ol der of perturbation theory. Following a strategy described in a previous publication, the O(a) counterterm required for on-shell improvement of the current is computed. We also confirm an earlier result of Wohlert for the coefficient in front of the SW term in the improved action.
