The $W$ Boson Loop Background to H -> ZZ at Photon-photon Colliders

Abstract

We have performed a complete one-loop calculation of $\gamma \gamma \to ZZ$ in the Standard Model, including both gauge bosons and fermions in the loop. We confirm the large irreducible continuum background from the $W$-boson loop found by Jikia. We have included the photon-photon luminosity, and find that the continuum background of transverse $Z$ boson pairs prohibits finding a heavy Higgs with mass $\gtap 350$ GeV in this decay mode.
