Prospect of heavy right-handed neutrino search at energies reached at the Superconducting Super Collider and CERN Large Hadron Collider

Abstract

Right-handed neutrinos with a large Majorana mass occur naturally in the left-right-symmetric model. We explore the prospect of such a heavy right-handed neutrino search via W_R decay in the like-sign dilepton channel at the Superconducting Super Collider (SSC) and CERN Large Hadron Collider (LHC). The standard model background can be effectively eliminated by suitable lepton p_T and isolation cuts without affecting the signal cross section seriously. In this way it seems possible to explore the bulk of the parameter space 0<M_NR<M_WR, with M_WR going up to 3000 (2000) GeV at energies reached at the SSC (LHC).
