LHC sensitivity to Kalzua-Klein gluon in two b-jets decay channel

Abstract

We examine a possibility to discover a Kaluza-Klein (KK) excitation of gluon in a warped extra dimension model at the Large Hadron Collider focusing on a decay channel of the KK gluon into a $b$-quark pair. It is known that, in a certain extension of the warped extra dimension model, the third generation quarks could strongly couple to the KK gluon owing to appropriate bulk fermion mass parameters. Taking account of kinematical cuts to reduce background events, we show the model parameter space which leads to a significance larger than 5$\sigma$ with the integrated luminosity of 10 (100) ${\mathrm{fb}}^{-1}$.
