Abstract
Heavy neutrinos can be discovered at LHC. Many extensions for Standard Model predict the existence of a new neutrino which has a mass at high energies. B-L model is one of them which predict the existence of three heavy (right-handed) neutrinos one per generation, new gauge massive boson and a new scalar Higgs boson which is different from the SM Higgs. In the present work we search for heavy neutrino in 4 leptons + missing energy final state events which are produced in proton-proton collisions at LHC using data produced from Monte Carlo simulation using B-L model at different center of mass energies. We predict that the heavy neutrinos pairs can be produced from 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 signature of new physics beyond Standard Model at higher energies at LHC.

Summary
Standard Model of elementary particles needs an extension to explain some facts. One of these facts is that the neutrinos are massive. The scale of the B-L symmetry breaking is related to the mass scale of the heavy right-handed Majorana neutrino mass [2,3], terms providing the wellknown see-saw mechanism of light neutrino mass generation. The model under consideration B-L symmetry-breaking is based on the gauge group. This model provides a natural explanation for the presence of three right-handed neutrinos, [4] and can account for the current experimental results of the light neutrino masses and their mixings. For the heavy be degenerate neutrino masses M and relatively light, vvharwyienwg iilnl take them the range
