Search for Heavy Majorana Neutrinos at LHC using Monte Carlo simulation

Abstract

Heavy neutrinos can be discovered at LHC. Many extensions for Standard Model predict by existing of new neutrino has a mass at high energies at LHC. B-L model one of them that predict by existence three heavy (right-handed) neutrinos one per generation, new gauge massive boson and new scalar Higgs boson rather than SM Higgs. In this work we search for heavy neutrino in 4 leptons + missing energy final state events produced in proton-proton collisions at LHC using data produced from Monte Carlo simulation for B-L model at different center of mass energies. We predict that the heavy neutrinos pairs can be produced from Z' B-L new gauge neutral massive boson decay and then the heavy neutrino pairs can decay to 4 leptons + missing energy final state which give us an indication for new signatures of new physics beyond Standard Model at higher energies at LHC for B-L extension of Standard Model .
