Electromagnetic decay of the Sigma^0(1385) to Lambda-gamma

The electromagnetic decay { Sigma}{sup 0}(1385){yields}{ 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{sup +}{ Sigma}{sup *0}. We report the decay widths ratio { Sigma}{sup 0}(1385){yields}{ Lambda}{gamma}/{ Sigma}{sup 0}(1385){yields}{ Lambda}{pi}{sup 0}=1.42{+-}0.12(stat){sub -0.07}{sup +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}{sup 0}(1385){yields}{ Lambda}{gamma}.
