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…

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…

Search for ( = 0, 1, 2) near GeV at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +399

We search for the ( = 0, 1, 2) processes at center-of-mass energies = 10.653, 10.701, 10.746, and 10.804 GeV. These data were collected with t…

Measurement of inclusive partial branching fractions and at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +419

A sample of 365 fb of data collected by the Belle II experiment is used to measure the partial branching fractions of charmless semileptonic…
