Study of τ- → KS π- ντ decay with Belle
The report presents a study of τ- → KS π- ντ decay using a data sample corresponding to an integrated luminosity of 351 fb-1 collected by the Belle detector. The analysis is based on 55017 lepton-tagged signal events. The measured branching ratio B (τ → KS π ντ) = (0.391 ± 0.004stat ± 0.014syst) % is consistent with the PDG value and has much better accuracy. © 2007 Elsevier B.V. All rights reserved.
