  The aim of this work is to search for a new heavy Higgs boson in the B-L
extension of the Standard Model at LHC using the data produced from simulated
collisions between two protons at different center of mass energies by Monte
Carlo event generator programs to find new Higgs boson signatures at the LHC.
Also we study the production and decay channels for Higgs boson in this model
and its interactions with the other new particles of this model namely the new
neutral gauge massive boson and the new fermionic right-handed heavy neutrinos .
