$Z\gamma$ production in association with two jets at next-to-leading order QCD

Abstract

Next-to-leading order QCD corrections to the QCD-induced $pp\to l^{+}{l}^{-}\gamma jj+X$ and $pp\to {\bar{\nu }}_l{\nu }_l\gamma jj+X$ processes are presented. The latter is used to find an optimal cut to reduce the contribution of radiative photon emission off the charged leptons in the first channel. As expected, the scale uncertainties are significantly reduced at NLO and the QCD corrections are phase space dependent and important for precise measurements at the LHC.
