Abstract
Using data samples collected with the BESIII detector at center-of-mass energies , 4.26, 4.36, and 4.42 GeV, we measure the branching fractions of , , , and , via the process , . The corresponding results are , , , and , respectively. Here the first uncertainties are statistical, and the second ones systematic. Additionally, the charged track multiplicity of decays is measured for the first time.
