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

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 ${\mathit{W}}_{\mathit{R}}$ 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 ${\mathit{p}}_{\mathit{T}}$ 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${\mathit{M}}_{\mathit{N}\mathit{R}}$${\mathit{M}}_{\mathit{W}\mathit{R}}$, with ${\mathit{M}}_{\mathit{W}\mathit{R}}$ going up to 3000 (2000) GeV at energies reached at the SSC (LHC).
