Abstract

Using 7.33 fb−1 of e+e− collision data collected by the BESIII detector at c.m. energies between 4.128 GeV and 4.226 GeV, we observe for the first time the decay Ds±→ωπ±η with a statistical significance of 7.6σ. The measured branching fraction of this decay is (0.54±0.12±0.04)%, where the first uncertainty is statistical and the second is systematic.Received 9 February 2023Accepted 13 March 2023DOI:https://doi.org/10.1103/PhysRevD.107.052010Published by the American Physical Society under the terms of the Creative Commons Attribution 4.0 International license.
