Probe of the electromagnetic moments of the tau lepton in gamma-gamma collisions at the CLIC

Abstract

We have investigated the electromagnetic moments of the tau lepton in ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{e}^{+}{\ensuremath{\gamma}}^{*}{\ensuremath{\gamma}}^{*}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{e}^{+}\ensuremath{\tau}\overline{\ensuremath{\tau}}{e}^{\ensuremath{-}}$ process at the CLIC. We have obtained 95% confidence level bounds on the anomalous magnetic and electric dipole moments for various values of the integrated luminosity and the center of mass energy. We have shown that the ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{e}^{+}{\ensuremath{\gamma}}^{*}{\ensuremath{\gamma}}^{*}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{e}^{+}\ensuremath{\tau}\overline{\ensuremath{\tau}}{e}^{\ensuremath{-}}$ process at the CLIC leads to a remarkable improvement in the existing experimental bounds on the anomalous magnetic and electric dipole moments.
