Search for Heavy Majorana Neutrinos at LHC using Monte Carlo simulation

TL;DR

This paper investigates the potential to discover heavy Majorana neutrinos at the LHC by simulating their production and decay in a B-L extended Standard Model, focusing on four-lepton plus missing energy signatures.

Contribution

It introduces a Monte Carlo simulation study of heavy neutrino production in B-L models at the LHC, highlighting new signatures beyond the Standard Model.

Findings

Heavy neutrino pairs can be produced from Z' decay.

Decay to four leptons plus missing energy is a key signature.

Potential for discovering new physics at higher LHC energies.

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 .
