A search for the lepton flavor violating decays τ-→l-KS0 (l=e or μ) has been performed using a data sample corresponding to an integrated luminosity of 469fb-1, collected with the BABAR detector at the SLAC PEP-II e+e- asymmetric energy collider. No statistically significant signal has been observed in either channel ; the estimated upper limits on branching fractions are B(τ-→e-KS0)<3.3×10-8 ; B(τ-→μ-KS0)<4. 0×10-8 at 90% confidence level. © 2009 The American Physical Society.

Abstract
A search for the lepton flavor violating decays τ-→l-KS0 (l=e or μ) has been performed using a data sample corresponding to an integrated luminosity of 469fb-1, collected with the BABAR detector at the SLAC PEP-II e+e- asymmetric energy collider. No statistically significant signal has been observed in either channel ; the estimated upper limits on branching fractions are B(τ-→e-KS0)<3.3×10-8 ; B(τ-→μ-KS0)<4. 0×10-8 at 90% confidence level. © 2009 The American Physical Society.File in questo prodotto:
