Abstract

The process e +e −→HZ will be the dominant source of Standard Model Higgs bosons at LEP200 and future e +e −-colliders with energies up to 500 GeV. We shortly review the corresponding lowest order cross section and discuss the O( α) electroweak corrections for the unpolarized as well as the polarized cross sections. The corrections are of the order of several percent at LEP200 energies. At high energies they are considerably enhanced for large values of the Higgs mass, transversely polarized Z-bosons, or in the forward and backward directions. Large corrections arise in particular from box diagrams.
