摘要：

We extend to the "unquenched" case the results of the perturbative calculation in lattice QCD with Wilson fermions of the mixing and renormalization coefficients of the operators entering into the expression of the lowest moment of the F2 structure function. We argue that the rank two finite operator with vanishing anomalous dimension that we construct for unlike indices, is to be identified with the lattice energy-momentum tensor. © 1990.
