Available in PDF, EPUB and Kindle. Book excerpt: A search for the lepton flavor violating decays?− → l− K{sub S}° (l = e or?) 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 ee− asymmetric energy collider. No statistically significant signal has been observed in either channel and the estimated upper limits on branching fractions are?(?− → e− K{sub S}°)
