The W Boson Loop Background to H -> ZZ at Photon-photon Colliders
M. S. Berger
Abstract
We have performed a complete one-loop calculation of γγ→ 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 350 GeV in this decay mode.
