We present a study of the semileptonic decay using an annihilation data sample of collected at the center-of-mass energy of 3.773 GeV with the BESIII detector. The branching fraction of is measured to be , which is a factor 1.6 more precise than previous measurements. By performing an amplitude analysis, we measure the hadronic form-factor ratios of at assuming the single-pole-dominance parametrization: and . Published by the American Physical Society 2024
