Abstract

We investigate the constraints on the anomalous quartic ZZγγ couplings through the process p p→ pγp→ p γq Z X at the LHC. Taking into consideration various forward detector acceptances and integrated LHC luminosities, we find 95% confidence level bounds on the anomalous coupling parameters. We show that the bounds on these couplings are at the order of 10^-6GeV^-2 which are about four orders of magnitude more restricted with respect to current experimental bounds.
