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...

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.

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.
