FOUR WEAK GAUGE BOSON PRODUCTION AT PHOTON LINEAR COLLIDER AND HEAVY HIGGS SIGNAL

摘要

We study the signals and backgrounds for a heavy Higgs boson in the processes gamma gamma --> WWWW, gamma gamma --> WWZZ at the photon linear collider. The results are based on the complete tree-level SM calculation for these reactions. We show that the invariant mass spectrum of central WW, ZZ pairs is sensitive to the signal from Higgs boson with a mass up to 1 TeV at a 2 TeV linear collider for integrated luminosity of 300 fb(-1). At 1.5 TeV PLC Higgs boson with a mass up to 700 GeV can be studied. The nonresonant longitudinal gauge boson scattering (m(H) = infinity) can be detected in photon-photon collisions at e(+)e(-) center-of-mass energy of 3 TeV. [References: 45]
