Expected sensitivity on the anomalous quartic neutral gauge couplings in $\gamma \gamma$ collisions at the CLIC

Abstract

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 $\gamma \gamma \rightarrow Z Z$ at the Compact Linear Collider with the center-of-mass energy of $\sqrt{s}=3$ TeV and integrated luminosity of $\mathcal{L}=5$ $\mathrm ab^{-1}$. 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: $f_{T0}/\Lambda ^{4}=[-1.06; 1.08]\times 10^{-3}$ $\mathrm{TeV^{-4}}$, $f_{T1}/\Lambda ^{4}=[-1.06; 1.08]\times 10^{-3}$ $\mathrm{TeV^{-4}}$,$f_{T2}/\Lambda ^{4}=[-1.06; 1.08]\times 10^{-3}$ $\mathrm{TeV^{-4}}$,$f_{T0}/\Lambda ^{4}=[-1.06; 1.08]\times 10^{-3}$ $\mathrm{TeV^{-4}}$, $f_{T5}/\Lambda ^{4}=[-4.08; 4.08]\times 10^{-4}$ $\mathrm{TeV^{-4}}$ and $f_{T8}/\Lambda ^{4}=[-1.10; 1.10]\times 10^{-4}$ $\mathrm{TeV^{-4}}$. Our results on the anomalous quartic neutral gauge couplings are set to a more stringent sensitivity concerning the recent experimental limits.
