Measurement of the τ lepton polarization and R(D∗) in the decay B¯→D∗τ−ν¯τ with one-prong hadronic τ decays at Belle

Abstract

With the full data sample of 772 × 10^6 BBbar pairs recorded by the Belle detector at the KEKB electronpositron collider, we report the measurement of the τ lepton polarization and R(D∗) in the decay B¯→D∗τ−ν¯τ with one-prong hadronic τ decays at Belle.
