We have analyzed 121.4 fb−1 of data collected at the Υ(5S) resonance by the Belle experiment using the KEKB asymmetric-energy e+e− collider to search for the decay B0s→J/ψπ0. We observe no signal and report an upper limit on the branching fraction B(B0s→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.

Abstract
We have analyzed 121.4 fb−1 of data collected at the Υ(5S) resonance by the Belle experiment using the KEKB asymmetric-energy e+e− collider to search for the decay B0s→J/ψπ0. We observe no signal and report an upper limit on the branching fraction B(B0s→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.File in questo prodotto:
