Description

We present the Large Hadron Collider (LHC) discovery potential in the Z' sector of a U(1)_{B-L} enlarged Standard Model (that also includes three heavy Majorana neutrinos and an additional Higgs boson) for sqrt{s}=7 and 14 TeV centre-of-mass (CM) energies, considering both the Z'_{B-L} -> e+e- and Z'_{B-L} -> µ+µ- decay channels. The run of the LHC at sqrt{s}=7 TeV, assuming at most ∫L ~ 1 fb-1, will be able to give similar results to those that will be available soon at the Tevatron in the lower mass region, and to extend them for a heavier M_{Z'}. Finally, the run at 14 TeV is needed to fully probe the parameter space and its potential is comparable in scope to that of a future TeV scale Linear Collider (LC). If no evidence is found in any energy configuration, 95% C.L. limits can be determined, and, given their better resolution, the limits from electrons will always be more stringent than those from muons.
