and also consider models with large brane kinetic terms [@Davoudiasl:2002ua] or an expanded custodial symmetry which protects the $Z$-$b$-$\bar{b}$ vertex from large corrections [@Agashe:2006at; @Contino:2006qr; @Carena:2007ua] in order to characterize the difference in the properties of the first KK mode of the gluon in each case. We find that there are general features which can discriminate between the cases, and thus that the specific realization of the RS model leaves an imprint in the properties of the KK gluon.

The article is laid out as follows: in section \[sec:models\], we review the specific details of the models under consideration. In Section \[sec:xsec\] we show the $g^1$ production rates and decay properties and show how the strong coupling can lead to interesting finite width effects in section \[sec:interfere\]. Section \[sec:conclusions\] contains our conclusions.

The Basic RS Model with the SM in the Bulk
------------------------------------------

The basic RS model is a slice of AdS$_5$ with the background metric $$ds ^2 =  \Big( \frac{z_h}{ z}\Big)^2  \left[ \eta_{ \mu \nu } 
d x ^{\mu } d x^{ \nu } + ( d z ) ^2  \right] , \label{metric-conf}$$ with curvature $\kappa  = 1/z_h \lesssim M_{Pl}$. $x^\mu$ are the coordinates of the
