Abstract

We have analyzed 121.4 fb-1 of data collected at the ?(5S) resonance by the Belle experiment using the KEKB asymmetric-energy e+e- collider to search for the decay Bs0→J/ψπ0. We observe no signal and report an upper limit on the branching fraction B(Bs0→J/ψπ0) of 1.21×10-5 at 90% confidence level. This result is the most stringent, improving the previous bound by 2 orders of magnitude.
