Probing violation of CP & T invariance in the transitions of τ leptons

Abstract

The SM predicts zero value for CP & T violation in the decays of τ leptons -except τ − → νK S [π − /π − π 0 ...]. Our community could establish impact of New Dynamics (ND) in a CP asymmetry in a semi-hadronic τ transition and later in a second one. To be 'practical', I suggest to our experimental colleagues to probeWhile I had mostly given comments about CP violation in τ transitions, some theorists have shown how ND models could produce CP asymmetries; I will discuss these ones, although sometimes I am not a true theorist, but as a phenomenalist here. I can hardly 'dream' that CP asymmetry in τ decays could connected with our huge asymmetry in 'our' matter vs. anti-matter.
