DOIAbstract
The electromagnetic decay Sigma(0)(1385) -> Lambda gamma 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(+)Sigma*(0). We report the decay widths ratio Sigma(0)(1385) -> Lambda gamma/Sigma(0)(1385) -> Lambda pi(0) = 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 Sigma(0)(1385) -> Lambda gamma
