YN scattering data: DO65

Authors: H.G. Dosch, R. Engelmann, H. Filthuth, V. Hepp, E. Kluge, A. Minguzzi-Ranzi
Reference: Phys. Lett. 14 (1965), 162
Group: Heidelberg

The experiment:

In the Saclay 81 cm Hydrogen Bubble Chamber which was exposed to a beam of K- mesons from the Proton-Synchroton at CERN. Reactions of the produced Σ particles were studied. 80000 pictures have been scanned. 71 Σ- p and Σ+ p scattering events are analyzed.
Preliminary results; final results in DO66.

The data:

Σ- p → Σ- p total elastic cross section (SGT)
momentum range      number of     SGT [mb]
    [MeV/c]          events

  140 -  170           26       232 +/- 47
Σ+ p → Σ+ p total cross section (SGT))
momentum range      number of     SGT [mb]
    [MeV/c]          events

  135 -  175           14       185 +/- 55
Σ- p → Σ0 n
Σ- p → Λ n
total cross section (SGT)
momentum range      number of     SGT [mb]
    [MeV/c]          events
