Analysis of the anomalous electromagnetic moments of the tau lepton in $\gamma p$ collisions at the LHC

Abstract

In this study, we investigate the potential of the process $pp\to p{\gamma }^{\ast }p\to p\tau {\bar{\nu }}_{\tau }{q}^{\prime }X$ at the LHC to examine the anomalous electromagnetic moments of the tau lepton. We obtain $95\%$ confidence level bounds on the anomalous coupling parameters with various values of the integrated luminosity and center-of-mass energy. The improved bounds have been obtained on the anomalous coupling parameters of electric and magnetic moments of the tau lepton $a_{\tau }$ and $|$$d_{\tau }$$|$ compared to the current experimental sensitivity bounds. The $\gamma p$ mode of photon reactions at the LHC have shown that it has great potential for the electromagnetic dipole moments studies of the tau lepton.
