Quartic anomalous couplings in gamma gamma colliders.

Abstract

We study the constraints on the vertices ${\mathit{W}}^{+}$${\mathit{W}}^{\mathrm{\ensuremath{-}}}$Z\ensuremath{\gamma}, ${\mathrm{W}}^{+}$${\mathrm{W}}^{\mathrm{\ensuremath{-}}}$\ensuremath{\gamma}\ensuremath{\gamma}, and ZZ\ensuremath{\gamma}\ensuremath{\gamma} that can be obtained from triple-gauge-boson production at the next generation of linear ${\mathit{e}}^{+}$${\mathit{e}}^{\mathrm{\ensuremath{-}}}$ colliders operating in the \ensuremath{\gamma}\ensuremath{\gamma} mode. We analyze the processes \ensuremath{\gamma}\ensuremath{\gamma}\ensuremath{\rightarrow}${\mathit{W}}^{+}$${\mathit{W}}^{\mathrm{\ensuremath{-}}}$V (V=Z or \ensuremath{\gamma}) and show that these reactions increase the potential of ${\mathit{e}}^{+}$${\mathit{e}}^{\mathrm{\ensuremath{-}}}$ machines to search for anomalous four-gauge-boson interactions.
