# Limits on Kaluza-Klein Gluons in Warped Extra Dimensions INSPIRE search

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 theExtra Dimensions'' review for more discussion.

1  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.
2  AAD 2013AQ use 4.7 fb${}^{-1}$ of data from ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV.
3  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.
4  AAD 2012BV use 2.05 fb${}^{-1}$ of data from ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV.
