Abstract
Influence of the neutrino mass submatrix ML on the e-e- -> W-W- process is discussed. Taking into account various possible CP signatures of heavy neutrinos it is shown that, in some cases, nonzero ML substantially changes predictions for maximum possible values of the e-e- -> W-W- cross section. A direct role of the ω2 parameter (coming from neutrinoless double beta decay) is clarified. The consequences of doubly charged Higgs particles δ-- with resonances even far away from energies of the future linear lepton collider (s=0.5-1 TeV) are studied.
