Discovering new gauge bosons of electroweak symmetry breaking at LHC-8

Abstract

We study the physics potential of the 8 TeV LHC (LHC-8) to discover, during its 2012 run, a large class of extended gauge models or extradimensional models whose low-energy behavior is well represented by an $SU(2{)}^{2}\ensuremath{\bigotimes}U(1)$ gauge structure. We analyze this class of models and find that, with a combined integrated luminosity of $40--60\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ at the LHC-8, the first new Kaluza-Klein mode of the $W$ gauge boson can be discovered up to a mass of about 370--400 GeV when produced in association with a $Z$ boson.
