Abstract
We study a possibility of observation of the first Kaluza-Klein (KK) excitation of gluon in a warped extra dimension model at the LHC. In our analysis, we adopt the KK gluon mass and the b-quark coupling to the KK gluon as model parameters and study the sensitivity of the ATLAS experiment to observe the KK gluon through the two $b$-jets channel.
Highlights
The Standard Model (SM) of particle physics has shown a good agreement with almost all data of high energy experiments, we expect new physics beyond the SM from some theoretical motivations such as a gauge hierarchy problem

We studied the possibility of observation of effects of the first excitation of a KK gluon, predicted by the extension of the Randall and Sundrum (RS) model
Summary
The Standard Model (SM) of particle physics has shown a good agreement with almost all data of high energy experiments, we expect new physics beyond the SM from some theoretical motivations such as a gauge hierarchy problem. We suppose the extension of the original RS model, where SM gluons can propagate into the bulk. In such a model, there are Kaluza-Klein (KK) excitations of gluons. We study a possibility of observation of the first KK excitation of gluon at the LHC. We adopt the KK gluon mass and the b-quark coupling to the KK gluon as model parameters and study the sensitivity of the ATLAS experiment to observe the KK gluon through the two b-jets channel. More detailed description and analysis is published in our paper [2]
