Abstract
We study the sensitivity of anomalous ZZγ and Zγγ vertex couplings h3γ,Z and h4γ,Z, which would be a powerful sign of new physics, via the subprocess γq→Zq of the main reaction pp→pγp→ZqX at the LHC. We calculated limits on these couplings at 95% confidence level for various values of integrated luminosity. It is shown that the pp→pγp→ZqX reaction provides 1 order of magnitude improvement in the couplings h4γ,Z compared to the current experimental limits obtained in events dominated by Zγ production from the LHC and Tevatron. © 2013 American Physical Society.
