T, C, P, CP symmetries, Accidental symmetries (B, L conservation)

Measurement of the helicity suppressed ratio of charged kaon leptonic decay rates BR(K --> e nu)/BR(K --> mu nu) has long been considered as an excellent test of lepton universality and the Standard Model (SM) description of weak interactions. It was realised recently that the suppression of the SM contribution might enhance the sensitivity to SUSY-induced effects to an experimentally...

T, C, P, CP symmetries, Accidental symmetries (B, L conservation)

We present the results of recent BABAR studies of narrow Upsilon states, in particular, tests of lepton universality, lepton flavour violation and direct searches for low-mass physics beyond the standard model.

T, C, P, CP symmetries, Accidental symmetries (B, L conservation)

We present the results of a search for lepton flavor violating tau decays and a search for CP violation in tau to nu K_S pi using a large data sample accumulated with the Belle detector at the KEKB asymmetric-energy e^+e^- collider. The sensitivity to these modes is significantly improved compared to previous experiments.
