Abstract:

Higgs-strahlung

e~+e~-\to ZH

and

WW

fusion

e~+e~-\to\bar\nu_e\nu_e H

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.
