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…
Study of via initial-state radiation at Belle~II
Belle II Collaboration, M. Abumusabh, I. Adachi +417
Using a data sample of 427.9 fb collected by the Belle~II detector at or near the and resonances, the cross sections for $(h=Ï/K…
First evidence of and search for
Belle, Belle II Collaborations, : +412
We search for the pionic transitions and in decays using the Belle and Belle~II data sam…
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…
