Abstract
The influence of the neutrino mass submatrix on the process is discussed. Taking into account various possible signatures of heavy neutrinos it is shown that, in some cases, a nonzero substantially changes predictions for maximum possible values of the cross section. The direct role of the parameter (coming from neutrinoless double-beta decay) is clarified. The consequences of doubly charged Higgs particles with resonances still far away from energies of the future linear lepton collider are studied.
