Eta' production in pi+ d interactions from threshold to 2.4 gev/c

Rader, R.K. ; Abolins, M.A. ; Dahl, O.I. ; et al.

Inspire Record 82914 DOI 10.17182/hepdata.22250

We have studied η′ production using a π+ beam incident on deuterium in the 72-in. bubble chamber, with beam momenta from 1.1 to 2.4 GeVc. Cross sections for reactions leading to five- and six-pronged final states are presented. We observe η′ production in the reaction π+d→ppη′, with the decay mode η′→π+π−η. The cross section for π+n→pη′ (studied in the impulse approximation) is observed to rise to a maximum of about 100 μb at 2.2-GeV c.m. energy. The production angular distribution develops peripheral peaking with increasing energy.

Sigma+ polarization in pi+ n ---> k0 sigma+ from 1.1 to 2.4 gev/c

Inspire Record 82052 DOI 10.17182/hepdata.22133

We observe an energy-dependent polarization of the Σ+ produced in the reaction π+n→K0Σ+ at incident beam momenta between 1.1 and 2.4 GeV/c. These data form a significant source of information on the Σ− polarization in the charge-symmetric reaction π−p→K+Σ−.

The inclusive single-particle spectra of pi-, K0(s) and Lambda in proton proton collisions at 19-GeV/c

The Scandinavian Bubble Chamber collaboration Boeggild, H. ; Dahl-Jensen, E. ; Hansen, K.H. ; et al.
Nucl.Phys.B 57 (1973) 77-99, 1973.
Inspire Record 84068 DOI 10.17182/hepdata.32535

Data on the inclusive production spectra of K S 0 and Λ from proton-proton collisions at 19 GeV are presented and discussed in connection with the earlier studied inclusive π − production spectrum. The three single-particle spectra are compared with a crude two-center thermal model for the average radiation from the pp collisions.

The differential cross section for the reaction π − p→n π ° has been measured with high statistics at six incident beam momenta between 1.0 and 2.4 GeV/ c . The results are compared with predictions of recent phase shift analyses and forward dispersion relations.

The Reaction pi- p ---> eta n at High-Energies

Dahl, O.I. ; Johnson, R.A. ; Kenney, R.W. ; et al.
Phys.Rev.Lett. 37 (1976) 80, 1976.
Inspire Record 108647 DOI 10.17182/hepdata.21028

Measurements on the reaction π−p→ηn have been carried out at Fermilab with beam energies from 20 to 200 GeV in the same experiment in which pion charge-exchange scattering was studied. The differential cross sections have a pronounced dip in the forward direction. The data can be described well by a simple Regge-pole model but the resulting A2 trajectory is not degenerate with the ρ trajectory extracted from the charge-exchange data.

Pion Charge Exchange Scattering at High-Energies

Barnes, A.V. ; Mellema, D.J. ; Tollestrup, A.V. ; et al.
Phys.Rev.Lett. 37 (1976) 76, 1976.
Inspire Record 108646 DOI 10.17182/hepdata.21046

We report on a study of pion charge-exchange scattering carried out at Fermilab in the energy range 20 to 200 GeV. The results can be described remarkably well by a simple Regge-pole model. The charge-exchange cross sections in the forward direction lead to a prediction for the difference in total cross sections of π−p and π+p which is in satisfactory agreement with direct measurements of this difference in another experiment at Fermilab.
