Tev Scale B-L Phenomenology At Lhc

We present the phenomenology of the low scale U(1)(B- L) extension of the standard model and its implications at LHC. We show that this model provides a natural explanation for the presence of three right-handed neutrinos and can naturally account the observed neutrino masses and mixing. We study the decay and production of the extra gauge boson and the SM singlet scalar ( heavy Higgs) predicted in this type of models. We find that the cross sections of the SM-like Higgs production are reduced by similar to 20%-30%, while its decay branching ratios remain intact. The extra Higgs has relatively small cross sections and the branching ratios of Z ' -> l(+) l(-) are of order similar to 20% compared to similar to 3% of the SM results.
