Anomalous quartic ZZgammagamma couplings in gamma-proton collision at
the LHC    [PDF]

I. Sahin, B. Sahin

We investigate the constraints on the anomalous quartic $ZZ\gamma\gamma$ couplings through the process $p p\to p\gamma p\to p \gamma q Z X$ 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.
