Experimental Review on Lepton Universality and Lepton Flavour Violation tests at the B-factories

Abstract

Since 1999, the B-factories collaborations BABAR and Belle have accumulated and studied large samples of tau lepton pairs. The experimental results on Lepton Universality checks and Lepton Flavour Violation searches are reported.
