Heavy Neutrino signals in models with extended lepton sector

Abstract

The gauge model SU (2)L × U (1) with extension of the lepton sector by right sterile Majorana neutrinos is considered. A block diagonalization of the total mass matrix 6 × 6 of light (active) and sterile neutrinos is performed for the general form of the mixing matrix in the sterile neutrino sector. Production rates and distributions for pTN and yN for processes pp → Nl± and pp → NV were studied including gluon fusion gg → h*/Z* → NV at s=13 Tev LHC energy.
