Searches for charged-lepton-flavor violation in decays
Belle, Belle II Collaborations, : +415
We report the first searches for charged-lepton-flavor violation in decays of ( and ) to a pair of charged leptons using 158 million decays collect…

Improved measurement of Born cross sections for and ( = 0, 1, 2) at Belle and Belle II
Belle, Belle II Collaborations, : +424
We study the processes and ( = 0, 1, 2) at center-of-mass energies from 10.73 to 11.02 GeV using a $142.5\,\mathrm{fb}^{…

Measurement of time-dependent asymmetries in decays at Belle and Belle II
Belle, Belle II Collaborations, : +350
We present a measurement of the time-dependent asymmetry in decays using a data set of 365 fb recorded by the Belle II experiment…
