Improved measurements of (Formula presented) and (Formula presented)

Using (Formula presented) of (Formula presented) collision data collected at the center-of-mass energy of 3.773 GeV with the BESIII detector, we measure the absolute branching fractions of (Formula presented), (Formula presented), (Formula presented), and (Formula presented) to be (Formula presented), (Formula presented), (Formula presented), and (Formula presented), respectively. By performing a simultaneous fit to the partial decay rates of these four decays, the product of the hadronic form factor (Formula presented) and the modulus of the (Formula presented) Cabibbo-Kobayashi-Maskawa matrix element (Formula presented) is determined to be (Formula presented). Taking the value of (Formula presented) from the standard model global fit or that of (Formula presented) from the lattice quantum chromodynamics calculation as input, we derive the results (Formula presented). and (Formula presented).
