Abstract

We study the sensitivity of anomalous $Z Z γ$ and $Z γ γ$ vertex couplings $h_{3}^{γ, Z}$ and $h_{4}^{γ, Z}$ , which would be a powerful sign of new physics, via the subprocess $γ q \to Z q$ of the main reaction $p p \to p γ p \to Z q X$ at the LHC. We calculated limits on these couplings at 95% confidence level for various values of integrated luminosity. It is shown that the $p p \to p γ p \to Z q X$ reaction provides 1 order of magnitude improvement in the couplings $h_{4}^{γ, Z}$ compared to the current experimental limits obtained in events dominated by $Z γ$ production from the LHC and Tevatron.
