摘要：

In this Letter we present the results from a calculation of the full electroweak one-loop corrections for gammaZ vector-boson pair production at hadron colliders. The cases of proton-antiproton as well as proton-proton collisions, at the Tevatron and the LHC, respectively, are considered. Results are presented for the distribution of the gammaZ invariant mass and for the transverse momentum of the final-state photon. The higher-order electroweak effects are numerically significant, in particular for probing possible anomalous gauge-boson couplings. (C) 2004 Elsevier B.V. All rights reserved.
