Abstract / Description:We search for the process $B^0 \\to \\pi^- \\tau^+ \\nu_\\tau$ using the full Belle data set of $711\\,{\\rm fb}^{-1}$, corresponding to $772 \\times 10^6 B\\bar{B}$ pairs, collected at the $\\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider. We reconstruct one $B$ meson in a hadronic decay and search for the $B^0 \\to \\pi^- \\tau^+ \\nu_\\tau$ process in the remainder of the event. No significant signal is observed and an upper limit of $\\mathcal{B}(B^0 \\to \\pi^- \\tau^+ \\nu_\\tau) < 2.5 \\times 10^{-4}$ is obtained at the $90\\%$ confidence level.
