Abstract

We search for the process B0πτ+ντ using the full Belle data set of 711fb1, corresponding to 772×106BB¯ pairs, collected at the ϒ(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 B0πτ+ντ process in the remainder of the event. No significant signal is observed and an upper limit of B(B0πτ+ντ)<2.5×104 is obtained at the 90% confidence level.
