Description

We investigate the reaction e-e- → W-W- in the center-of-mass energy regime far above threshold for W-pair production. We assume lepton-flavour violation to be mediated by a Majorana mass matrix for six neutrino flavours as is natural in SO(10) assignments. We show that the cross section compatible with constraints from low energy may well be detectable at √s = 0.5 TeV under conservative assumptions on neutrino mixing angles and masses. The dependence on center-of-mass energy α(√x)4 may thus lead to sizable rates at 1-2 TeV. (orig.)
