$\gamma Z$ Pair Production at the Photon Linear Collider

Abstract

$\gamma \gamma \to \gamma Z$ scattering at the Photon Linear Collider is considered. Explicit formulas for helicity amplitudes due to $W$ boson loops are presented. It is shown that the $Z\gamma$ pair production will be easily observable at PLC and separation of the $W$ loop contribution will be possible at $e^{+}{e}^{-}$ c.m. energy of 300~GeV or higher.
