YN scattering data: BA67
The experiment:
Λ p interactions leading to final states of the
types Λ p,
Λ p π π and Σ p π have been studied.
150000 pictures have been scanned.
68 elastic events have been recorded.
The data:
|
Λ p → Λ p
|
total elastic cross section (SGT)
|
|
|
momentum range number of SGT [mb]
[MeV/c] events
1000 - 2250 25 12 +/- 4
2250 - 3500 27 9 +/- 3
3500 - 5000 8 9 +/- 4

Notes:
-
Other inelastic cross sections have been measured.
-
Some information on the angular distribution of the events is given
in a graph. PDG extracted numbers from these graphs. We do not include
these.
-
PDG calculated F/B = 1.00 +/- 0.14 from the angular
distribution mentioned in the previous note. (Events from 2.5 - 5 GeV/c)
