AbstractAbstract
[en] The aim of the experiment performed at the CERN-PS hyperon beams was the study of elastic scattering and diffraction and dissociation of SIGMA minus in the following processes: SIGMA minus+P→X-+P (X=SIGMAminus elastic scattering, X=Y resonance production). The elastic SIGMAminus cross section has been measured at 17.2 GeV/c in the interval -0.12, -0.38(GeV/c)2. After parametrization the SIGMAminus slope is b=8.12+-0.35(GeV/c)-2. At the same energy the diffraction dissociation of SIGMAminus in the channels Y*→Λ0π- and Y*→SIGMAneutral π- is studied

Le but de l'experience realisee sur le faisceau d'hyperons du PS du CERN etait d'etudier la diffusion elastique et la production de resonance des interactions SIGMA-+P→X-+P (X=SIGMA- diffusion elastique, X=Y production de resonance). La section differentielle elastique a ete mesuree a 17 GeV/c dans l'intervalle de transfert t=-0.12, -0.38(GeV/c)2. Apres parametrisation, la position du SIGMA moins est b=8.12+-0.35 (GeV/c)2. A la meme energie on a essaye de mettre en evidence la production diffractive de Y* dans les canaux Y*→Λ0π- et Y*→SIGMA0π-Original Title
