$Z'$ discovery potential at the LHC in the minimal $B-L$ extension of the Standard Model

Understand

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 $\sqrt{s}=7$, 10 and 14 TeV centre-of-mass (CM) energies, considering both the $Z'_{B-L}\rightarrow e^+e^-$ and $Z'_{B-L}\rightarrow \mu^+\mu^-$ decay channels.

• The comparison of the (irreducible) backgrounds with the expected backgrounds for the D$\O$ experiment at the Tevatron validates our simulation.
• We propose an alternative analysis that has the potential to improve the D$\O$ sensitivity.
• Electrons provide a higher sensitivity to smaller couplings at small $Z'_{B-L}$ boson masses than do muons.
