Belle, Belle II Collaborations, : +412
We search for the pionic transitions and in decays using the Belle and Belle~II data sam…
First search for decays
Belle II Collaboration, M. Abumusabh, I. Adachi +440
We report the first search for the flavor-changing neutral-current decays , where is a hadronic system with strangeness equal to 1, in data co…
Search for sub-GeV dark particles in decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +685
Using (1008744)10 events collected with the BESIII detector at the BEPCII collider at the center-of-mass energy of , we report th…
First Measurement of the Absolute Branching Fraction of
BESIII Collaboration, M. Ablikim, M. N. Achasov +691
We apply a tag-and-probe method to precisely measure the absolute branching fraction of the decay with the BESIII experiment at BEPCII. Starting with a large initia…
