Electroweak radiative corrections to single Higgs-boson production in e+e− annihilation

We have calculated the complete electroweak O(α) radiative corrections to the single Higgs-boson production processes e+e−→νlν̄lH (l=e,μ,τ) in the electroweak Standard Model. Initial-state radiation beyond O(α) is included in the structure-function approach. The calculation of the corrections is briefly described, and numerical results are presented for the total cross-section. In the Gμ scheme, the bulk of the corrections is due to initial-state radiation, which affects the cross-section at the level of −7% at high energies and even more in the ZH threshold region. The remaining bosonic and fermionic corrections are at the level of a few percent. The confusing situation in the literature regarding differing results for the fermionic corrections to this process is clarified.
