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 .

Elastic scattering of anti-protons on protons at 5 gev/c evidence for a backward peak

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

Phys.Lett.B 38 (1972) 449-451, 1972.

Inspire Record 75820 DOI 10.17182/hepdata.5678

Antiproton-proton elastic scattering has been measured at 5 GeV/c. A total of 30 000 events were observed in the angular range 17° < θ cm < 136°, corresponding to 0.3 < − t < 7.7 (GeV/ c 2 ). In addition to the known dip at − t = 0.5 ( GeV / c ) 2 , we observe a structure at about − t = 2 (GeV/ c ) 2 and a backward peak with a slope4.1 ± 0.6 (GeV/ c ) 2 . The extrapolated differential cross-section at u = 0 is 1.3 ± 0.8 μ b/(GeV/ c ) 2 .

Upper limits on rare two-body processes in k- p and anti-p p scattering at high energies

Birnbaum, D. ; Edelstein, R.M. ; Hien, N.C. ; et al.

Phys.Lett.B 31 (1970) 36-39, 1970.

A missing mass spectrometer search was made for several two-body, double charge exchange reactions, including backward K −p and p̄p elastic scattering at 8 and 16 GeV/ c and small momentum transfer. No examples of any of these processes were observed.

Anti-p-p elastic scattering at 8 and 16 gev/c

Phys.Rev.Lett. 23 (1969) 663-666, 1969.

Inspire Record 56380 DOI 10.17182/hepdata.3393

Angular distributions are presented for p¯−p elastic scattering at 8 and 16 GeV/c for |t|<1.3 (GeV/c)2. At both energies there is structure in the differential cross sections in the region 0.5<~|t|<~1.0 (GeV/c)2, similar to that observed at lower energies. The diffraction peak continues to expand with increasing incident momentum.
