TL;DR: In this article, the average number of produced pions in a 2 m hydrogen bubble chamber was investigated and the particle multiplicities in the final states and single-particle momentum spectra were presented.

TL;DR: The p p elastic differential cross section at 50 GeV/c has been measured in a two-arm spectrometer experiment at the CERN SPS as mentioned in this paper, where a pronounced dip-bump structure is observed with a sharp minimum at | t | = 1.5 (GeV/ c ) 2.

Evidence for dominance of Pomeron like exchange in pp → NNπ at 19 GeV/c
H. Bøggild,K. H. Hansen,H. Johnstad,R. Møllerud,M. Suk,L. Veje,M. Korkea-Aho,K.V. Laurikainen,P. Laurikainen,V. Bakken,S. Bjåstad,F.O. Breivik,T. Jacobsen,S.O. Sørensen,O. Danielsson,G. Ekspong,L. Grantstrøm,B.E. Ronne +17 more
TL;DR: In this article, the amplitudes with the low mass Nπ system in isospin states 1 2 and 3 2 were analyzed at 19 GeV/c and analyzed in terms of the amplitude amplitudes of the I − 1 2 cross section.

The four-prong annihilation of 1.2 GeV/c antiprotons in hydrogen (I): Four-pion final state
R.A. Donald,D.N. Edwards,R.S. Moore,E.J.C. Read,S. Reucroft,A.G. Frodesen,T. Jacobsen,S. Sire,O. Skjeggestad,P. Saetre,H. Tøfte,A. Bettini,S. Limentani,L. Peruzzo,R. Santangelo,S. Sartori +15 more
TL;DR: In this article, the center-of-mass angular distributions of the pions are presented, and a change in the momentum dependence of the forward-backward asymmetry of pions is observed at a pion momentum corresponding to the production of A2±π+.

Exchange mechanisms and energy dependence of isospin amplitudes for the reaction pN → NNπ in the energy range 5–1480 GeV☆
E. Dahl-Jensen,I. Dahl-Jensen,J. D. Hansen,R. Møllerud,J. Mäkelä,M. Pimiä,E. Sundell,V. Bakken,J. Haldorsen,T. Jacobsen,G. Skjevling,G. Ekspong,H. Johansson,P. Lundborg,B. Sellden +14 more
TL;DR: In this article, the isoscalar amplitude M 1 2 0 is interpreted to be dominated by pomeron exchange and the isovector amplitude M 3 2 1 by π exchange, where Ix and I are the isospins of the exchanged particle and the N4π combination respectively.
