Abstract

Coherent Λπ- production on Pb of 600 GeV Σ- hyperons has been studied with the SELEX facility at Fermilab. Using the Primakoff formalism, we set a 90% CL upper limit on the radiative decay width Γ[Σ(1385)-→Σ -γ]<9.5 keV, and estimate the cross section for γΣ-→Λπ- at s≈1.385 GeV to be 56±16 μb.
