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…

First measurements of the branching fractions for the decay modes and and search for the decay using Belle and Belle II data
Belle, Belle II Collaborations, : +321
Using data samples of 988.4 fb and 427.9 fb collected with the Belle and Belle II detectors, we present a study of the singly Cabibbo-suppressed decays $Ξ_c^{0} \to Λ…
