Abstract
- Physical review / D 105(1), 012007 (2022). doi:10.1103/PhysRevD.105.012007<br />We report results from a search for the decay B0s→ηη using 121.4 fb−1 of data collected at the Υ(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.<br />Published by APS, Melville, NY
