$\tau -\mu -e$ Universality in $\tau$ Decays and Constraints on the Slepton Masses

P. H. Chankowski, R. Hempfling, S. Pokorski

The leptonic $\tau$ decays are calculated at the 1-loop level in the Minimal Supersymmetric Standard Model. The deviation from the $\tau -\mu -e$ universality is studied as a function of t…
