Anomalous quartic and triple gauge couplings in $\gamma$-induced processes at the LHC

TL;DR

This paper investigates the potential to detect anomalous quartic and triple gauge couplings in photon-induced W/Z pair production at the LHC, using forward proton detectors to explore physics beyond the Standard Model.

Contribution

It provides sensitivity estimates for anomalous gauge couplings at the LHC considering leptonic decay channels and forward proton detection, extending the search for new physics.

Findings

Sensitivity to anomalous couplings improves with higher luminosity.

Probing beyond Standard Model physics with forward detectors is feasible.

Results can test Higgsless and extra dimension models.

Abstract

We study the $W/Z$ pair production via two-photon exchange at the LHC and give the sensitivities on trilinear and quartic gauge anomalous couplings between photons and $W/Z$ bosons for an integrated luminosity of 30 and 200 fb$^{-1}$. For simplicity and to obtain lower backgrounds, only the leptonic decays of the electroweak bosons are considered. The intact protons in the final states are detected in the ATLAS Forward Proton detectors. The high energy and luminosity of the LHC and the forward detectors allow to probe beyond standard model physics and to test the higgsless and extra dimension models in an unprecedent way.
