Upper limit on the decay Sigma(1385)- --> Sigma- gamma, and cross section for gamma Sigma- --> Lambda pi-

SELEX Collaboration, V. V. Molchanov

Coherent Lambda pi- production on Pb of 600 GeV Sigma- hyperons has been studied with the SELEX facility at Fermilab. Using the Primakoff formalism, we set a 90% CL upper limit on…
