On the lowest order electroweak corrections to spin-12 fermion scattering: (II). The one-loop amplitudes

A calculation of the one-loop electroweak corrections to the scattering of spin-12 fermions within the Weinberg-Salam-like theory is continued. A renormalization scheme based on a natural choice of input parameters, i.e. electron charge e and the masses of all particles (Mw, Mz, Mx and fermion masses mf is considered indetail. This scheme is generalized to a theory with arbitrary unitary mixing of fermion fields. The one-loop amplitudes for fermion decays of W, Z and x bosons and for μ decay are also calculated. The radiative correctionsto the vector boson masses and the renormalization of the parameter sin2 θw are discussed.
