Abstract

In this paper we discuss the possibility of measuring the anomalous magnetic and electric dipole moments of the $\tau$ lepton. The method consists in studying the spin precession induced by the strong effective magnetic field inside channels of a bent crystal with a dedicated setup at the CERN Large Hadron Collider.
