We present the results of a search for the flavor-changing neutral-current rare decays and using a data sample that contains events. The data were collected at the resonance with the Belle detector at the KEKB asymmetric-energy collider. We find no evidence for signal and set upper limits on branching fractions at the 90% confidence level in the range depending on the decay channel. The obtained limits are the world’s best results. This is the first search for the channels and . Published by the American Physical Society2024more » « less
