Probing anomalous triple gauge boson couplings via photon-photon scattering at the LHC

In this paper we study the anomalous triple gauge boson couplings (aTGCs) via proton-proton collisions at the high luminosity phase of LHC through the process of central exclusive production pp→pWWγp at the center of mass energy 14 TeV and integrated luminosity 3 ab^(-1). In this study to reduce the background processes, the leptonic decay of bosons is considered. In order to distinguish this process from inclusive processes in proton-proton collision, final intact protons must be detected. For this purpose, we use the feature of the forward detectors embedded at a distance of about two hundred meters on both sides of the proton interaction point and a few millimeters transverse distance from the proton beam. Using the kinematics of the particles produced in the central detector and their dependence on the kinematics of the intact protons in the very forward region, we set the appropriate cuts and obtained the expected limits on aTGCs. Comparing the obtained results with the existing experimental limits indicates that this process can be considered as a complementary process to the study of these couplings and improve the existing limits on the aTGCs.
