Abstract

The Standard Model (SM) of the electroweak has proven to be successful in describing all the available precision experimental data. However, the Higgs mechanism, responsible for the electroweak symmetry breaking in the SM, still remains one of the most important open questions of the theory. The effect of new operators that give rise to anomalous Higgs boson coupling to two photons (HAA) is examined in the two-photon processes AA -> H \to bb, AA,W+W-,ZZ at a high energy linear e+ e- collider (NLC).
