Аннотация

We report the first measurement of the D^∗− meson polarization in the decay B⁰ → D^∗−τ⁺ν_τ using the full data sample of 772×10⁶ BB^¯ pairs recorded with the Belle detector at the KEKB electron-positron collider. Our result, F_L^D∗ = 0.60 ±0.08(stat) ±0.04(sys), where F_L^D∗ denotes the D^∗− meson longitudinal polarization fraction, agrees within about 1.7 standard deviations of the standard model prediction.
