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.…

Searches for charged-lepton-flavor violation in decays

Belle, Belle II Collaborations, : +425

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…

First measurement of the masses of the and states and the energy dependence of the cross sections for and

Belle, Belle II Collaborations, : +398

We study the processes and at center-of-mass energies =(10.73 -- 11.02) GeV using a data sampl…

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…

Search for , , and dibaryons in and decays at Belle

Belle, Belle II Collaborations, : +367

We search for , , and dibaryon states in and decays, probing mass regions near the corresponding baryon-pair thresholds. Multistrange baryon…

Upgrade of the Belle II Vertex Detector with Depleted Monolithic CMOS Active Pixel Sensors

Belle II VTX Collaboration

The Belle II experiment, operating at the asymmetric SuperKEKB collider, is preparing an upgrade of its vertex detector to cope with an increased luminosity of $6 \times 1…
