$ZZγ$ and $Zγγ$ anomalous couplings in $γp$
collision at the LHC    [PDF]

We study the sensitivity of anomalous $ZZ\gamma$ and $Z\gamma\gamma$ vertex couplings $h_3^{\gamma,Z}$ and $h_4^{\gamma,Z}$, which would be powerful sign of new physics, via the subprocess $\gamma q\to Z q$ of the main reaction $pp\to p\gamma p\to Z q X$ at the LHC. We calculated limits on these couplings at 95\% confidence level for various values of integrated luminosity. We show that our limits on the couplings $h_4^{V}$ are one order better than the experimental limits obtained in events dominated by $Z\gamma$ production from LHC and Tevatron.
