Search for the decay
Belle, Belle II Collaborations, : +432
We present the first search for decays. We look for signal decays in events produced in asymmetric-energy electron-positron collisions.…

Measurement of the branching fraction, polarization, and time-dependent asymmetry in decays and constraint on the CKM angle
Belle II Collaboration, I. Adachi, L. Aggarwal +377
We present a measurement of the branching fraction and fraction of longitudinal polarization of decays, which have two 's in the final state. We also meas…
