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.
