Finally, both Belle and BaBar searched for CLFV [tau] [right arrow] l + h(s) decays, where a charged lepton of the same sign of the tau is emitted together with a combination of pseudoscalar or vector hadrons (e.g., [tau] [right arrow] l[[pi].sup.0], [tau] [right arrow] l[omega], [tau] [right arrow] l[[pi].sup.+][[pi].sup.-], etc.).
