Observation of small angle proton proton elastic scattering at 30 gev and 45 gev center-of-mass energies

Holder, M. ; Radermacher, E. ; Staude, A. ; et al.

Small angle elastic scattering events have been observed at the CERN Intersecting Storage Rings. Directions of both particles as well as the collision vertex are reconstructed with the help of four sets of spark chambers, two for each of the two arms. The elastic nature of the events is demonstrated by a collinearity requirement. We find values for the (diffraction) slope parameter in disagreement with the simple linear extrapolation of lower energy (Surpukov) data.

Experimental comparison of anti-d p and anti-p d total cross-sections

Denisov, S.P. ; Donskov, S.V. ; Gorin, Yu.P. ; et al.
Phys.Lett.B 34 (1971) 167-169, 1971.
Inspire Record 69336 DOI 10.17182/hepdata.5847

d ̄ p and p ̄ d total cross-sections have been measured at 13.3 and 6.65 GeV/ c respectively to check CPT-invariance. The standard transmission technique was used. The difference of d ̄ p and p ̄ d total cross-sections appeared to be equal 0.2 ± 2.6 mb. In addition d ̄ d and p ̄ p total cross-sections have been obtained. The experimental data allowed us to derive the total cross-section of antineutrons on protons, neutrons and deutrons.

Xi- production in 5.5-gev/c k- p interactions

Goldwasser, Edwin L. ; Schultz, P.F. ;
Phys.Rev.D 1 (1970) 1960-1966, 1970.
Inspire Record 61710 DOI 10.17182/hepdata.25069

Final states with a Ξ− hyperon have been studied in 5.5-GeV/c K−p interactions. Center-of-mass production angular distributions for the Ξ− have a peak in the beam direction, while those for the K+ or K0 meson peak in the opposite direction. Approximately half of the observed events involve the Ξ*(1530) or K*(890) resonances. The four- and five-body final states show production of the Ξ*(1930) in the Ξ−π+,0 mass spectrum and a narrow peak at 2295 MeV in the Ξ−π+π− mass spectrum. The mass of the Ξ− hyperon is 1321.9±0.5 MeV as determined from 195 Ξ− decays with a visible Λ decay, assuming a Λ-hyperon mass of 1115.58 MeV.

Anti-proton-neutron elastic scattering at 3.5 gev/c

We have measured the p¯n differential elastic cross section for −t≥0.15 (GeV/c)2. We compare our data with existing data from p¯p and np elastic scattering experiments in this energy region. Our data show a dip in the cross section at −t≃0.45 (GeV/c)2 and a secondary maximum at −t≃0.7 (GeV/c)2. We see no evidence for backward peaking in p¯n elastic scattering at this energy. Evidence is presented for I=1, t-channel exchange in N¯N scattering.

On the separation of single and double scattering in proton-deuteron collisions at 19.2 gev/c

Allaby, J.V. ; Diddens, A.N. ; Glauber, R.J. ; et al.
Phys.Lett.B 30 (1969) 549-554, 1969.
Inspire Record 63236 DOI 10.17182/hepdata.28891

Experimental data exhibiting the separation of single and double quasi-elastic scattering in proton-deuteron collisions at 19.2 GeV/ c and for momentum transfers around 1 GeV/ c are presented. An analysis of the scattering cross section in terms of the multiple scattering theory is given. The possibilities for the deduction of proton-neutron differential cross sections particularly at large momentum transfers are pointed out.
