Observation of the radiative decay

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

We observe the radiative decay for the first time, with a significance exceeding standard deviations. The signal is found in the conti…

Improved measurement of Born cross sections for and ( = 0, 1, 2) at Belle and Belle II

Belle, Belle II Collaborations, : +424

We study the processes and ( = 0, 1, 2) at center-of-mass energies from 10.73 to 11.02 GeV using a $142.5\,\mathr…

Search for decays at the Belle II experiment

Belle II Collaboration, I. Adachi, K. Adamczyk +446

We present a search for the rare flavor-changing neutral-current decay with data collected by the Belle II experiment at the SuperKEKB electron-posit…

Measurement of asymmetries in decays at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +399

We describe a measurement of charge-parity () violation asymmetries in decays using Belle II data. We consider and $η'\toρ(\toπ^…
