Expected sensitivity on the anomalous quartic neutral gauge couplings in γγ collisions at the CLIC

The non-Abelian gauge structure of the Standard Model (SM) implies the presence of multi-boson self-interactions. Precise measurements of these interactions allow testing the nature of the SM and new physics contributions arising from the beyond SM. The investigation of these interactions can be approached in a model-independent manner using an effective theory approach, which forms the main motivation of this study. In this paper, we examine the anomalous neutral quartic gauge couplings through the process yy -> ZZ at the Compact Linear Collider with the center-of-mass energy of =3 TeV and integrated luminosity of =5 a-1. The anomalous neutral quartic gauge couplings are implemented into FeynRules to generate a UFO module inserted into Madgraph to create background and signal events. These events are passed through Pythia 8 for parton showering and Delphes to include realistic detector effects. We obtain that the sensitivities on the anomalous quartic neutral gauge couplings with 95% Confidence Level are given as: 0/Lambda 4=[-1.06;1.08]x10-3 TeV-4, 1/Lambda 4=[-1.06;1.08]x10-3 TeV-4,2/Lambda 4=[-1.06;1.08]x10-3 TeV-4,0/Lambda 4=[-1.06;1.08]x10-3 TeV-4, 5/Lambda 4=[-4.08;4.08]x10-4 TeV-4 and 8/Lambda 4=[-1.10;1.10]x10-4 TeV-4. Our results on the anomalous quartic neutral gauge couplings are set to a more stringent sensitivity concerning the recent experimental limits
