Abstract

The electromagnetic decay Σ0(1385)→Λγ was studied using the CLAS detector at the Thomas Jefferson National Accelerator Facility. A real photon beam with a maximum energy of 3.8 GeV was incident on a proton target, producing an exclusive final state of K+Σ *0. We report the decay widths ratio Σ0(1385) →Λγ/Σ0(1385)→Λπ0=1.42±0.12(stat) -0.07+0.11(sys)%. This ratio is larger than most theoretical predictions by factors ranging from 1.5-3, but is consistent with the only other experimental measurement. From the reported ratio we calculate the partial width and electromagnetic transition magnetic moment for Σ0(1385) →Λγ.
