Kaluza-Klein gluons at 100 TeV: NLO corrections

TL;DR

This paper assesses the potential of a 100 TeV collider to detect KK gluons, analyzing their production at NLO and highlighting the importance of higher-order corrections for accurate predictions.

Contribution

It provides the first detailed NLO calculation of KK gluon production at a 100 TeV collider within warped extra dimension models, including scale dependence analysis.

Findings

NLO corrections are negative, with a K-factor around 0.7.

Residual scale dependence is approximately ±20%.

Results are consistent with previous lower-energy collider studies.

Abstract

We explore the reach of a 100 TeV proton collider to discover KK 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 RS 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 with a residual scale dependence on the order of $\pm 20\%$, greater than the variation from the scale exhibited by the na\"{i}ve LO estimate.
