Abstract: (Elsevier)
We discuss the explicit construction of a regularized, e.g. lattice, chiral gauge theory, with or without elementary Higgs fields. In contrast with the vector-like case of QCD, the regularization breaks the chiral gauge invariance. We argue that such a breaking can be compensated by adding all possible, renormalizable counterterms to the naive lattice action. The requirement that the Green functions thus computed satisfy the Slavnov-Taylor identities of BRST symmetry determines the coefficients of the counterterms.
