This search uses ϒ(1S) mesons produced in ϒ(2S) → π+π− ϒ(1S) transitions. We do not find any significant signal, so we provide upper limits on the branching fractions at the 90% confidence level.application/pdfenCreative Commons Attribution 4.0 InternationalArticle - Refereed2022-05-22The Author(s)https://doi.org/10.1007/JHEP05(2022)095
