QCD Corrections and Anomalous Couplings in $Z\gamma$ Production at Hadron Colliders

U. Baur, T. Han, J. Ohnemus

The processes $pp/pbarp\to Z\gamma +X\to {\ell }^{+}{\ell }^{-}\gamma +X$ ($\ell =e,\mu$) and $pp/pbarp\to Z\gamma +X\to \bar{\nu }\nu \gamma +X$ are calculated to $\mathcal{O}({\alpha }_s)$ for general $ZZ\gamma$ and $Z\gamma \gamma$ c…
