Anomalous quartic ZZγγ couplings in γp collision at the LHC

We investigate the constraints on the anomalous quartic ZZ gamma gamma couplings through the process pp -> p gamma p -> p gamma qZX 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(-6) GeV-2 which are about four orders of magnitude more restricted with respect to current experimental bounds.
