The effects of a strongly interacting Higgs sector on $\gamma\,\gamma\rightarrow W_L^+\,W_L^-, Z_L^{\,0}\,Z_L^{\,0}$ scattering

Abstract

We study the effects of a strongly interacting Higgs sector on the amplitudes for $\gamma\,\gamma\rightarrow W_L^+\,W_L^-, Z_L^{\,0}\,Z_L^{\,0}$ by unitarizing the $W_L^+\,W_L^-, Z_L^{\,0}\,Z_L^{\,0}, \gamma\,\gamma$ system using the $K$--matrix technique. Unitarization produces substantial corrections to the cross sections for gauge boson pair production by photon fusion when $m_H \agt 5-10\;$TeV.
