Abstract: The phenomenology of the low scale U1 {B-L} extension of the standard modeland its implications at LHC is presented. In this model, an extra gauge bosoncorresponding to B-L gauge symmetry and an extra SM singlet scalar heavyHiggs are predicted. We show a detailed analysis of both heavy and lightHiggses decay and production in addition to the possible decay channels of thenew gauge boson. We find that the cross sections of the SM-like Higgsproduction are reduced by ~ 20%-30%, while its decay branching ratios remainintact. The extra Higgs has relatively small cross sections and the branchingratios of Z-> l^+ l^- are of order ~20% compared to ~ 3% of the SM resuls.Hence, the search for Z is accessible via a clean dilepton signal at LHC.
