Higgs and Z' Phenomenology in B-L extension of the Standard Model at LHC

Understand

The phenomenology of the low scale U(1)_{B-L} extension of the standard model and its implications at LHC is presented.

• In this model, an extra gauge boson corresponding to B-L gauge symmetry and an extra SM singlet scalar (heavy Higgs) are predicted.
• We show a detailed analysis of both heavy and light Higgses decay and production in addition to the possible decay channels of the new gauge boson.
• We find that the cross sections of the SM-like Higgs production are reduced by ~ 20%-30%, while its decay branching ratios remain intact.
