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…
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 the lepton-flavor-violating decays at Belle II
Belle II Collaboration, I. Adachi, L. Aggarwal +447
We present the result of a search for the charged-lepton-flavor violating decays , where is a muon or an electron, using a data sampl…
