Remarks concerning the renormalized coupling constants of the gauge theories

Some basic properties of renormalized coupling constants are discussed in the framework of spontaneously broken gauge symmetries. It is pointed out that conventional definitions lead to some difficulties connected with infra-red divergences and two possible solutions are suggested. The ultraviolet d...

description Some basic properties of renormalized coupling constants are discussed in the framework of spontaneously broken gauge symmetries. It is pointed out that conventional definitions lead to some difficulties connected with infra-red divergences and two possible solutions are suggested. The ultraviolet divergent contributions to the lowest-order particular examples, how these divergent terms cancel in the interrelations between renormalized coupling constants and masses. The specific calcula-tions are carried out in the unitary gauge of the SU2xU1 gauges model, using thev-dimensional regularization method.
