Z' production in 331 models

Abstract

We analyse the possibilities to detect a new Z boson in di-electron events at LHC in the framework of the 331 model with right-handed neutrinos. For an integrated luminosity of 100 f b −1 at LHC, and considering a central value M Z = 1500 GeV, we obtain the invariant mass distribution in the process pp → Z → e + e − , where a huge peak, corresponding to 800 signal events, is found above the SM background. The number of di-electron events vary from 10000 to 1 in the mass range of M Z = 1000 − 5000 GeV.
