公開日期: | 2022 | 卷: | 105 | 期: | 1 | 來源出版物: | Physical Review D | 摘要: | We report results from a search for the decay Bs0→ηη using 121.4 fb-1 of data collected at the (5S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We do not observe any signal and set an upper limit on the branching fraction of 14.3×10-5 at 90% confidence level. This result represents a significant improvement over the previous most stringent limit. ? 2022 authors. Published by the American Physical Society. |
