Abstract

The phenomenological study of neutral heavy gauge boson (ZBLZ^{\prime}_{B-L}) of the minimal B-L extension was done on the dimuon production channel of the LHC. The study begins with the LEP-II constraints on ZZ' searches, and the dimuon events are simulated at the parton level at the CM energies of 7 TeV and 8 TeV and studied with an integrated luminosity of 1.21 fb1fb^{-1} and 20.5 fb1fb^{-1} respectively. Later, the ATLAS detector-specific cuts unique to the Muon Pairs are imposed followed by the signal-selection-cuts on the Invariant Mass of the dimuon which restrict the events that are to be passed for Signal-Background Analysis, that are finally compared with the ATLAS data, and accounted for no experimental detection of ZBLZ^{\prime}_{B-L} boson. It has been simulated further at the CM energy of 14 TeV with an integrated luminosity of 300 fb1fb^{-1} to predict a possible discovery of this B-L neutral-heavy gauge boson with a mass corresponding to 1.5 TeV and a ZZ' coupling strength of 0.2 based on the signal-background analysis.
