Production of doubly charged vector bilepton pairs at $\gamma \gamma$ colliders

Abstract

The production of pairs of doubly charged vector bileptons is studied at future $\gamma \gamma$ colliders. The unpolarized cross--section for the $\gamma \gamma \to Y^{--}{Y}^{++}$ subprocess is analytically calculated and convoluted to predict the number of events in the complete $e^{+}{e}^{-}\to \gamma \gamma \to Y^{--}{Y}^{++}$ process. The gauge or non--gauge character of the vector bilepton $Y^{\pm \pm }$ is discussed. It is found that as a consequence of its spectacular signature, as it decays dominantly into two identical charged leptons, and also due to its charge contents, which significantly enhance the cross--section, the detection of this class of particles with mass in the sub--TeV region can be at the reach of these colliders. The model--independent nature of our results is stressed.
