ONE PION PRODUCTION IN ANTI-PROTON PROTON INTERACTIONS AT 8.8-GEV/C

Simmons, A.J. ; Ansorge, R.E. ; Booth, C.N. ; et al.
Nucl.Phys.B 172 (1980) 285, 1980.
Inspire Record 158991 DOI 10.17182/hepdata.34497

We present a study of the reactions p p → p p π 0 , p p → p n π + , and p p → n p π − at 8.8 GeV/ c . Cross sections for the reactions are given, and the main features of the data are shown. The data are compared with the predictions of the Deck model, and evidence is presented for the presence of baryon exchange in the Deck amplitude.

Single Pion Production in anti-Proton-Proton Interactions

Stenbacka, R. ; Ekspong, G. ; Holmgren, S.O. ; et al.
Nucl.Phys.B 135 (1978) 20-44, 1978.
Inspire Record 134909 DOI 10.17182/hepdata.35129

Single-pion production in p p interactions at 9.1 GeV/ c is analysed and cross sections are given. The p lab dependence of the isospin amplitudes is determined by a fit to the world data. The data are also compared with the predictions of a reggeized Deck model. The results and the N π N amplitudes are compared with the results at other energies and with the corresponding N π N amplitudes.
