Electroweak radiative corrections to associated<i>WH</i>and<i>ZH</i>production at hadron colliders

Higgs-boson production in association with W or Z bosons, $p\overline{p}\ensuremath{\rightarrow}WH/ZH+X,$ is the most promising discovery channel for a light standard model Higgs particle at the Fermilab Tevatron. We present the calculation of the electroweak $O(\ensuremath{\alpha})$ corrections to these processes. The corrections decrease the theoretical prediction by up to 5%--10%, depending in detail on the Higgs-boson mass and the input-parameter scheme. We update the cross-section prediction for associated WH and ZH production at the Tevatron and at the CERN LHC, including the next-to-leading order electroweak and QCD corrections, and study the theoretical uncertainties induced by factorization and renormalization scale dependences and by the parton distribution functions.
