We observe no signal and report an upper limit on the branching fraction $\\mathcal{B}(B_s^0\\to J/\\psi\\pi^0)$ of $1.21\\times 10^{-5}$ at 90\\% confidence level. This result is the most stringent, improving the previous bound by two orders of magnitude.", "revisions": [ { "version": "v1", "updated": "2023-11-21T16:56:41.000Z" } ], "analyses": { "keywords": [ "belle experiment", "kekb asymmetric-energy", "upper limit", "confidence level", "branching fraction" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
