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.…
Search for axion-like particles decaying to two photons at Belle II
Belle II Collaboration, M. Abumusabh, I. Adachi +450
Axion-like particles (ALPs) are predicted in many extensions of the Standard Model and provide a well-motivated portal between visible and hidden sectors through their coupling to…
Charged-lepton identification at Belle~II
Belle II Collaboration, M. Abumusabh, I. Adachi +409
Effective particle identification capabilities are a strategic priority for the physics program of the Belle~II experiment. We describe the algorithms used at Belle~II for identify…
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…
Charged-hadron identification at Belle II
Belle II Collaboration, I. Adachi, H. Ahmed +408
The Belle II experiment's ability to identify particles critically affects the sensitivity of its measurements. We describe Belle II's algorithms for identifying charged particles…
Measurement of asymmetries in decays at Belle II
Belle II Collaboration, I. Adachi, L. Aggarwal +436
We report measurements of time-dependent asymmetries in decays based on a data sample of events collected at the $Î¥(4…
