Abstract
We present a study of Michel parameters in leptonic Ï decays using experimental information collected at the Belle detector. Michel parameters are extracted in the unbinned maximum likelihood fit of the (Ïââââνν; ϱâϱÏ0ν) (â=e, μ) events in the full nine-dimensional phase space. We exploit the spin-spin correlation of tau leptons to extract ξÏξ and ξÏξδ in addition to the Ï and η parameters. Sensitivity of the method and systematic effects will be discussed.
