Limits on Kaluza-Klein Gluons in Warped Extra Dimensions

INSPIRE   PDGID:
S071KKG
This section places limits on the mass of the first Kaluza-Klein (KK) excitation of the gluon in warped extra dimension models with Standard Model fields propagating in the bulk. Bounds are given for a specific benchmark model with $\Gamma /\mathit m$ = 15.3$\%$ where $\Gamma $ is the width and $\mathit m$ the mass of the KK gluon. See the``Extra Dimensions” review for more discussion.

1  AABOUD 2018BI use 36.1 fb${}^{-1}$ of data from ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV. This result updates AAD 2013AQ.
2  TUMASYAN 2022C use 138 fb${}^{-1}$ of data from ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV to place limits on a KK gluon decaying to gluons via a spin-0 radion, ${{\mathit R}}$. See their Figure 5 for limits on the cross section times branching fraction as a function of the KK gluon mass and various values of the radion mass.
3  AABOUD 2019AS use 36.1 fb${}^{-1}$ of data from ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV. An upper bound of 3.4 TeV is placed on the KK gluon mass for ${{\mathit \Gamma}}/{{\mathit m}}$ = 30$\%$.
4  SIRUNYAN 2019AL use 35.9 fb${}^{-1}$ of data from ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV to place limits on a KK gluon decaying to a top quark and a heavy vector-like fermion, T. KK gluon masses between 1.5 and 2.3 TeV and between 2.0 and 2.4 TeV are excluded for T masses of 1.2 and 1.5 TeV, respectively.
5  CHATRCHYAN 2013BM use 19.7 fb${}^{-1}$ of data from ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV. Bound is for a width of approximately $15 - 20\%$ of the KK gluon mass.
6  CHEN 2013A place limits on the KK mass scale for a specific warped model with custodial symmetry and bulk fermions. See their Figures 4 and 5.
7  AAD 2012BV use 2.05 fb${}^{-1}$ of data from ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV.
