Heavy quark expansion for the inclusive decay $\overline{B}$ --> $\tau\overline{\nu}$X
We calculate the differential decay rate for inclusive $\bar B\to\tau\ \bar\nu\,X$ transitions to order $1/m_b^2$ in the heavy quark expansion, for both polarized and unpolarized tau leptons. We show that using a systematic $1/m_b$ expansion significantly reduces the theoretical uncertainties in the...
