Resumo

The radiative decay Λ(1520)→Λγ was measured directly in the study of the exclusive diffractive-like reaction p+N→Λ(1520)K++N, Λ(1520)→Λγ with the SPHINX spectrometer. The values of the branching and partial width of this radiative decay were obtained: BR[Λ(1520)→Λγ]=(1.02±0.21(stat)±0.15(syst))×10−2 and Γ[Λ(1520)→Λγ]=159±33(stat)±26(syst) keV.
