Abstract

In this paper we show how to calculate analytically the oneloop helicity amplitudes for the process qbarq to tbart induced by KK gluon using the spinor helicity formalism A minimal set of Feynman rules which are uniquely fixed by gauge invariance and the color representation of the KK gluon are derived and used in the calculation Our results can be applied to a variety of models containing a massive color octet vector boson
