Abstract

The CLAS detector was used to obtain the first ever measurement of the electromagnetic decay of the Σ ^*+(1385) from the reaction γp→K0Σ ^*+(1385). A real photon beam with a maximum energy of 3.8 GeV was incident on a liquid-hydrogen target, resulting in the photoproduction of the kaon and Σ ^* hyperon. Kinematic fitting was used to separate the reaction channel from the background processes. The fitting algorithm exploited a new method to kinematically fit neutrons in the CLAS detector, leading to the measured decay widths ratio Σ ⁺(1385)→Σ ⁺γ/Σ ⁺(1385)→Σ ⁺π0=11. 95±2.21(stat)-1.21+0.53(sys)% and a deduced partial width of 250.0±56.9(stat)-41.2+34.3(sys)keV. A U-spin symmetry test using the SU(3) flavor-multiplet representation yields predictions for the Σ ^*+(1385)→Σ ⁺γ and Σ ^*0(1385)→Λγ partial widths that agree with the experimental measurements.
