Search for $B^0\to {\pi }^{-}{\tau }^{+}{\nu }_{\tau }$ with hadronic tagging at Belle

Belle Collaboration, P. Hamer, A. Frey +181

We search for the process $B^0\to {\pi }^{-}{\tau }^{+}{\nu }_{\tau }$ using the full Belle data set of $711{\mathrm{fb}}^{-1}$, corresponding to $772\times 10^{6}B\bar{B}$ pairs, collected at the ${\rm Y}(4S)$ r…
