K- p elastic scattering at 10-GeV/c

The Aachen-Berlin-CERN-London-Vienna collaboration Bartsch, J. ; Deutschmann, M. ; Kraus, G. ; et al.
Nucl.Phys.B 29 (1971) 398-404, 1971.

Results are presented on elastic scattering of 10.1 GeV/ c K − mesons on protons, based on a sample of 16 261 kinematically-fitted bubble-chamber events. The differential cross section is given over the | t |- range of 0.06 to 2.5 GeV 2 and is fitted with the expressions a e bt , A e Bt + Ct 2 and ( P e Qt + Re St ) over various intervals of t . The results are compared with those of other experiments at nearby energies. Upper limits of | α | < 0.28 and σ B < 0.4 μ b (both at a 90% confidence level) are given for the ratio of real to imaginary part of the forward-scattering amplitude and the backward-elastic-scattering cross section, respectively.

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.

Evidence for dominance of pomeron like exchange in p + p ---> n + n + pi at 19 gev/c

The reactions pp → NN π are studied at 19 GeV/ c and analysed in terms of the amplitudes with the low mass N π system in isospin states 1 2 and 3 2 respectively. The I − 1 2 cross section is compared with the corresponding one in π p→ ππ N at 8 GeV/ c .

Interaction of Positive Pions with Hydrogen at 600 MeV

Newcomb, Peter C.A. ;
Phys.Rev. 132 (1963) 1283-1292, 1963.
Inspire Record 47245 DOI 10.17182/hepdata.26734

The Berkeley 15-in. hydrogen bubble chamber was used to investigate π+−p interactions at 600 MeV. There were 1738 good events, of which 71.9±0.8% were elastic. Partial waves up to at least D52 are required to fit the elastic angular distribution. The inelastic events were almost entirely single-pion production. The ratio (p+0)(n++) was found to be 5.5±0.8 which agrees well with 4.9 predicted by the (32, 32) pion-nucleon isobar model of Olsson and Yodh. It is also consistent with 6.5 predicted by Sternheimer and Lindenbaum. The pion momentum spectra and the π−π Q-value distributions also support the Olsson and Yodh model. Thus the (32, 32) pion-nucleon isobar is apparently the principal mechanism for single-pion production at 600 MeV. Angular distributions for the single-pion-production data are presented.
