Productions and Decays of Heavy Neutrinos

Abstract

Within the left-right-symmetric models (LRM) the possibilities of detecting the neutrino dipole magnetic moments are investigated. The motion of the high-energy light neutrino beam in the twisting magnetic field and condensed matter is considered. The analysis of the resonance conversions has demonstrated that in the LRM only two schemes are possible: (i) the heavy neutrino masses are (quasi)-degenerated; (ii) these masses are arbitrary but the mixing angles between light and heavy neutrinos are zero. Processes of the heavy neutrinos production at hadron colliders are also studied.
