Abstract
We calculate the radiative corrections to semileptonic decays of hadrons, mediated by the W boson, within the context of SU(2)×U(1)×G models, proposed by de Groot, Gounaris, and Schildknecht, which allow for an arbitrary number N of neutral weak gauge bosons. In particular we analyze the large & behavior of the O(α) corrections and we generalize a theorem by Sirlin on these corrections formulated in the standard model.
