Higgs-strahlung and WW fusion in e+e− collisions

Higgs-strahlung e+e− → ZH and WW fusion e+e− → νeνeH are the most important mechanisms for the production of Higgs bosons in e+e− collisions at LEP2 and future e+e− linear colliders. We have calculated the cross sections and energy/angular distributions of the Higgs boson for these production mechanisms. When the Z boson decays into (electron-) neutrinos, the two production amplitudes interfere. In the cross-over region between the two mechanisms the interference term is positive and of the same size as the individual cross sections, thus enhancing the production rate.
