Effects of Lorentz violation through the gamma e arrow right W [nu] sub(e) process in the Standard Model extension

Physics beyond the Fermi scale could show up through deviations of the gauge couplings predicted by the electroweak Yang-Mills sector. This possibility is explored in the context of the International Linear Collider through the helicity amplitudes for the gamma e [rarr] Wv[sube] reaction to which the trilinear WW gamma coupling contributes. The new physics effects on this vertex are parametrized in a model-independent fashion through an effective electroweak Yang-Mills sector, which is constructed by considering two essentially different sources of new physics. We focus our study on the possibility of experimentally distinguishing both types of new physics effects on the WW gamma vertex. It is found that for a new physics scale of the same order of magnitude and under determined circumstances, both types of new physics effects will be clearly distinguished.
