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.…

Study of decays at Belle and Belle II

Belle, Belle II Collaborations, : +412

We report a measurement of the branching fraction for the leptonic decay . This work presents the first result using Belle~II data, an updated Be…

Measurement of mixing-induced CP violation in the decay

Belle II Collaboration, M. Abumusabh, I. Adachi +437

Measurements of charge-parity (CP) violation in quark transitions provide stringent tests of the current theory and sensitive probes of particles or interactions beyond it. We repo…

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…

Measurement of time-dependent violation parameters in decays at Belle and Belle II

Belle, Belle II Collaborations, : +416

We perform a measurement of time-dependent violation parameters in decays using a dataset of approximately and $521 \times 10…

Measurements of electroweak penguin and lepton-flavor violating B decays to final states with missing energy at Belle and Belle II

Gaetano de Marino

The Belle and Belle II experiments have collected a 1.2 ab sample of collisions at a center-of-mass energy corresponding to the resonance. These datasets, with low…
