Contribution

It provides the first comprehensive NLO QCD predictions for W gamma j production with full leptonic decay and off-shell effects at hadron colliders.

Findings

Corrections are sizable and significantly impact differential distributions.

The calculations include leptonic W decays with off-shell effects.

Results are relevant for precision measurements at Tevatron and LHC.

Abstract

We calculate the $W^\pm\gamma j + X$-production cross sections at next-to-leading order QCD for Tevatron and LHC collisions. We include leptonic decays of the $W$ to light leptons, with all off-shell effects taken into account. The corrections are sizable and have significant impact on the differential distributions.
