Riassunto analitico
A search for the lepton flavour violating decays tau-&gt;lKs has been performed using a data sample corresponding to an integrated luminosity of 469 fb-1, collected with the BABAR <br>detector at the SLAC PEP-II e+e− asymmetric energy collider, a selection optimized to obtain the best sensitivity, and the &#34;Modified Frequentist analysis&#34;. No statistically significant signal has been observed in either channel and the estimated upper limits on branching fractions are B(tau-&gt;e Ks) &lt; 3.3e-8 and B(tau-&gt;muKs) &lt; 4.0e-8 at 90% confidence level. <br><br>
