Abstract: (arXiv)
We present measurements of and decays using a combined data sample of pairs collected by the Belle experiment and pairs collected by the Belle II experiment in collisions at the resonance. After an optimized selection, a simultaneous fit to the Belle and Belle II data sets yields and decays. The measured branching fractions are and for and decays, respectively, where the first uncertainty is statistical and the second is systematic. We also measure the isospin asymmetry and the direct CP asymmetry .Note:
