QCD corrections and anomalous couplings in Zγ production at hadron colliders

The processes pp((-))-->Z gamma+X-->l(+)l(-)gamma+X (l = e,mu) and pp((-))-->Z gamma y+X-->(v) over bar v gamma+X are calculated to O(alpha(s)) for general ZZ gamma and Z gamma gamma couplings. The impact of O(alpha(s)) QCD corrections on the observability of ZZ gamma and Z gamma gamma couplings in Z gamma production at the Fermilab Tevatron and the CERN Large Hadron Collider (LHC) is discussed.
