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

Understand

Next-to-leading order QCD corrections to the QCD-induced $pp \rightarrow l^+l^- \gamma j j +X$ and $pp \rightarrow \bar{\nu}_l \nu_l \gamma jj+X$ 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.
