Vacuum Properties of the Σ(1385)+ Resonance
Description
We present data taken employing a proton beam incident on a liquid hydrogen target with a kinetic energy of 3.5 GeV. A total statistics of ≅ 1.2.109 events was collected by the High Acceptance Di-Electron Spectrometer (HADES) and analysed to study the properties of the Σ(1385)+-resonance. A clear signal corresponding to a peak of the Breit-Wigner parametrization of M = 1382.98±0.79MeV/c2 and a width of Γ0 = 38.78±2.03 MeV/c2 was extracted. The investigation of the differential production cross- section shows a strong anisotropy in the angular distribution of the Σ(1385)+-hyperon with respect to the beam direction in p+p collisions.
