$\tau$ magnetic moment in a $\gamma \gamma$ collider

Abstract

We analyze different observables to study the magnetic dipole moment of the tau pairs produced by photon linear colliders. We use the circular polarized photon beam and study distributions of polarized $\tau$ final pairs to define sensibly asymmetries to magnetic dipole moment.
