Production of a KK-graviton in association with a boson via gluon fusion at the LHC

Abstract

We discuss the processes where a KK-graviton ($G$) of the extra-dimensional models is produced in association with a color singlet boson via gluon fusion at the LHC. In particular, we consider the processes $gg\to hG$, $\gamma G$, $ZG$. These processes occur at one-loop through box and triangle diagrams. The cross-section for the process $gg\to \gamma G$ vanishes at the one-loop level. It can be understood by introducing the charge conjugation transformations of the KK-graviton. The processes $gg\to hG$, $ZG$ can be observed at the LHC if the KK-graviton and the Higgs boson exist with appropriate properties.
