Riassunto analitico
A search for the lepton flavour violating decays tau->lKs has been performed using a data sample corresponding to an integrated luminosity of 469 fb-1, collected with the BABAR
detector at the SLAC PEP-II e+e− asymmetric energy collider, a selection optimized to obtain the best sensitivity, and the "Modified Frequentist analysis". No statistically significant signal has been observed in either channel and the estimated upper limits on branching fractions are B(tau->e Ks) < 3.3e-8 and B(tau->muKs) < 4.0e-8 at 90% confidence level.
