Kaluza-Klein gluons at 100 TeV: NLO corrections


We explore the reach of a 100 TeV proton collider to discover Kaluza-Klein gluons in a warped extra dimension. These particles are templates for color adjoint vectors that couple dominantly to the top quark. We examine their production rate at NLO in the six-flavor m-ACOT scheme for a variety of reference models defining their coupling to quarks, largely inspired by the Randall-Sundrum model of a warped extra dimension. In agreement with previous calculations aimed at lower-energy machines, we find that the NLO corrections are typically negative, resulting in a K factor of around 0.7 (depending on the model) and a residual scale dependence on the order of ±20%, greater than the variation from the scale exhibited by the naïve LO estimate.
