dc.description.abstractThe process is considered as an example of the problems associated with maintaining gauge invariance in matrix elements involving unstable particles. It is shown how to construct a matrix element that correctly treats width effects for the intermediate unstable boson and that is both and gauge-invariant. gauge-invariance is maintained by Laurent expansion in kinematic invariants and gauge-invariance is enforced by means of projection operator under which the exact matrix element is invariant.en_US
