One Loop Weak Corrections to gamma/Z Hadroproduction At Finite Transverse Momentum

We illustrate the effects of one-loop weak corrections onto the production of neutral gauge bosons of the Standard Model at RHIC-spin, Tevatron and LHC, in presence of quark/gluon radiation from the initial state. We find such effects to be rather large, up to ${cal O}(10-20%)$ in typical observables at all such colliders, where the cross section is measurable, thus advocating their inclusion in precision analyses
