Abstract
We have searched for the baryon-containing radiative penguin decays and using a sample of events collected at the with the CLEO detector. We find no evidence for either, and set 90% confidence level upper limits of From the latter, we estimate This limit implies upper limits on corrections to CLEO’s recent measurement of branching fraction, mean photon energy, and variance in photon energy from that are less than half the combined statistical and systematic errors quoted on these quantities.
