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 $B^{0} \to I ¨ ^{0} I ¨ ^{0}$

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…

Observation of the radiative decay $D_{s} (2317)^{+} \to D_{s}^{*} I^^{3}$

Belle II Collaboration, M. Abumusabh, I. Adachi +367

We observe the radiative decay $D_{s 0}^{*} (2317)^{+} \to D_{s}^{*+} I^^{3}$ for the first time, with a significance exceeding $10$ standard deviations. The signal is found in the conti…
