· Physical Review. D.
Based on a data sample of events collected with the BESIII detector at the BEPCII collider, the M1 transition with is studied, where is or . The mass and width of the are measured to be and , respectively. The product branching fraction is determined to be . Using , we obtain the branching fraction of the radiative transition to be , where the third uncertainty is due to the quoted . Published by the American Physical Society 2024
