Abstract

We investigate the constraints on the anomalous quartic $Z Z γ γ$ couplings through the process $p p \to p γ p \to p γ q Z X$ 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 $10^{- 6} {GeV}^{- 2}$ which are about four orders of magnitude more restricted with respect to current experimental bounds.
