Radiative decays of the Σ0(1385) and Λ(1520) hyperons

Published

Journal Article

The electromagnetic decays of the Σ0(1385) and Λ(1520) hyperons were studied in photon-induced reactions γp→K+Λ(1116) γ in the Large Acceptance Spectrometer detector at the Thomas Jefferson National Accelerator Facility. We report the first observation of the radiative decay of the Σ0(1385) and a measurement of the Λ(1520) radiative decay width. For the Σ0(1385)→Λ(1116)γ transition, we measured a partial width of 479±120(stat)-100+81(sys)keV, larger than all of the existing model predictions. For the Λ(1520)→Λ(1116) γ transition, we obtained a partial width of 167±43(stat)- 12+26(sys)keV. © 2005 The American Physical Society.
