Eide, A. ; Lehmann, P. ; Lundby, A. ; et al.

Nucl.Phys.B 60 (1973) 173-220, 1973.

Inspire Record 83926 DOI 10.17182/hepdata.7885

We present results of measurements of K ± p and p p elastic scattering and of the annihilation reactions p p →π + π − and p p → K + K − at an incident laboratory momentum of 5 GeV/ c . Nearly complete angular distributions were obtained. Results are also presented for π -meson proton elastic scattering in the momentum transfer ranges 2 < − t < 8 (GeV/ c ) 2 (for π + ) and 0.16 < − t < 7 (GeV/ c ) 2 (for π − ). All measurements were done in one experimental geometry. The measured differential cross sections range from 10 to 10 −5 mb/(GeV/ c ) 2 .

K+- p elastic scattering at 5 gev/c. evidence for a k- p backward peak

Chabaud, V. ; Eide, A. ; Lehmann, P. ; et al.

Phys.Lett.B 38 (1972) 445-448, 1972.

Inspire Record 75816 DOI 10.17182/hepdata.5729

The elastic scattering of K ± mesons on protons has been studied at 5 GeV/c. A total of about 500 000 events have been measured in the c.m. angular range 17° < θ cm < 165° corresponding to 0.2 < − t < (GeV/ c ) 2 . We observed a K − p backward peak which we have parametrized as d σ /d u = (0.6 ± 0.2) exp [(3.3 ± 0.6) u ] μb /(GeV/c) 2 , while for the K + p backward peak we find d σ /d u = (17.5 ± 1) exp [(3.6 ± 0.2) u ] μb /(GeV/c) 2 . The K − p cross-section falls to about 0.03 μ b ( GeV /c) 2 around − t = 5 (GeV/ c ) 2 , while the K + p cross-section stays in the vicinity of 0.3 μ b ( GeV /c) 2 in the same t -region. The K + p and K − p differential cross-sections have cross-over points at − t = 0.2, 1.1 and about 3.5 (GeV/ c ) 2 .

Brunet, J.M. ; Narjoux, J.L. ; Danysz, J.A. ; et al.

Nucl.Phys.B 36 (1972) 45-57, 1972.

Inspire Record 75386 DOI 10.17182/hepdata.33006

Cross sections are presented for the K + p interacttions with 2, 3, 4 and 5 particles in the final state for incident momenta between 2.1 and 2.7 GeV/c. The results are compared with those from other experiments at nearby momenta.
