Abstract
We study Higgs boson production in association with a pair of electroweak vector bosons ( WW, ZZ, Zγ) at future e + e − colliders in the framework of the Standard Model. Total cross sections and distributions for the intermediate-mass Higgs are presented, with special emphasis on the Next Linear Collider (NLC) case operating at a centre-of-mass energy √ s≅500 GeV, where the cross sections turn out to be more favourable than in larger-√ s collisions. We find that with an integrated luminosity of 20 fb −1 there is sizeable event rate for the HWW and HZγ (with a high p T γ channels, while a larger integrated luminosity is needed to study the HZZ production. We take into account various backgrounds, notably top-pair and triple vector-boson production, and show ways to significantly reduce their effects.
