Sensitivities on the anomalous quartic $\gamma \gamma \gamma \gamma$ and $\gamma \gamma \gamma Z$ couplings at the CLIC

Abstract

It is essential to directly investigate the self-couplings of gauge bosons in the Standard Model (SM) due to its non-Abelian nature, as these couplings play a significant role in comprehending the gauge structure of the model. The discrepancies between the Standard Model's expectations and the measured value of gauge boson self-couplings would serve as strong evidence towards the existence of new physics phenomena that extend beyond the Standard Model. Such deviations could provide valuable insights into the nature of new physics and potentially lead to a deeper understanding of fundamental particles and their interactions. In this study, we examine the sensitivities of anomalous couplings associated with dimension-8 operators that affect the $\gamma \gamma \gamma \gamma$ and $Z\gamma \gamma \gamma$ quartic vertices. The study focuses on the process $e^{-}\gamma \to e^{-}\gamma \gamma$ with the incoming photon under Weizsäcker-Williams approximation at the stage-3 scenerio of Compact Linear Collider (CLIC) that is refer to a CoM energy of 3 TeV. Due to the CLIC options, we take into account the both unpolarized and $\mp 80\%$ polarized electron beam with the related integrated luminosities of $\mathcal{L}=5,4,1$ $\mathrm{a}{\mathrm{b}}^{-1}$ under the systematic uncertainties of ${\delta }_{sys}=0,3,5$. Obtained sensitivities on the anomalous quartic gauge couplings (aQGCs) for the process $e^{-}\gamma \to e^{-}\gamma \gamma$ at $\sqrt{s}=3$ TeV and various polarizations, are improved by a factor of 2-200 times better for the couplings $f_{T,j}/{\Lambda }^4$ compared with the experimental results.
