On the specific features of regularization of nondiagonal amplitudes in a unitary gauge
Description
On the example of the SU(2)xU(1) gauge theory the regularization procedure for different nondiagonal amplitudes is defined in a special unitary gauge. This gauge is not usually used for the fear of ambiguities, though it has some advantages due to a sharp decrease of the number of diagrams of the fixed order. A formulae for the regularized selfenergy and vertex operators are obtained and an explanation is given for the meaning of regularized vertex functions in unitary gauge. In conclusion a correctness of calculations with the help of the developed formalism is demonstrated on two examples
