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 120 - 160 31 450 +/- 100 |
Notes:
-
The data are not corrected for Coulomb effects.
- The ratio (Σ0)/(Σ0 + Λ) was determined based on a sample of 481 events: 0.39 +/- 0.03
