摘要

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