Higgs Boson Contributions to Neutrino Production in e-e+ Collisions in a Left-Right Symmetric Model

In gauge models with bigger number of Higgs particles their couplings to fermions are more complicated then in the standard model (SM). The influence of the Higgs bosons exchange on the neutrino production cross section in $e^-e^+$ collision ($e^-e^+ \rightarrow νN$) is investigated. The study has been done in the framework of the left-right symmetric model with the rich Higgs sector containing bidoublet and two triplets. The couplings of the Higgs particles even to light leptons can be as large as the gauge bosons couplings. The total effect of the Higgs bosons is small as a result of the big Higgs mass in the propagators.

CP Violation in the Heavy Neutrinos Production Process $e^+e^-\rightarrow N_1N_2$

The problem of CP conservation and CP violation for two heavy neutrinos production in $e^+e^-$ interaction is considered. Very convenient way of parametrization of the neutrino mass matrix, from which necessary and sufficient condition for CP conservation easily follows, is presented. Contrary to the Kobayashi-Maskawa mechanism, the effects of CP violation in the lepton sector with Majorana neutrinos can be very large. Change of the total cross section caused by CP violation can be much larger then the cross section itself.
