Possibility of Determining $\tau$ Lepton Electromagnetic Moments in $\gamma \gamma \to {\tau }^{+}{\tau }^{-}$ Process at the CERN-LHC

Abstract

Potential of the LHC to determine the electromagnetic couplings of the $\tau$ lepton is discussed via the process ${\gamma \gamma \to {\tau }^{+}\tau }^{-}$. Highly improved constraints of the anomalous magnetic and electric dipole moments have been obtained compared to the LEP sensitivity.
