摘要: The complete electroweak O(α) radiative corrections to the Higgs-boson production processes e + − → νllH (l = e, �, τ ) are calculated in Standard Model. For νe¯ νeH, where ZH and W-boson fusion contribute, both channels added coherently. calculation of is described some de- tail including, particular, treatment Z-boson resonance ZH-production channel. discussion numerical results focusses on total cross section as well angular energy distributions Higgs boson. In G� -scheme, bulk due initial-state radiation. turn out reduce by ∼ 10% for high energies, dominates. this region, depend only weakly angle Based an analysis leading universal corrections, a simple improved Born approximation introduced. This describes corrected within about 3%.
