title = "A two component model of two body nucleon diffraction dissociation and comparison with πp interactions at 3.9 GeV/c",
abstract = "We have studied π±p reactions at 3.9 GeV/c. This paper presents some of the results of a cross channel analysis of the π(N π) final state, the measurements for the diffraction dissociation channels of the individual cross sections and the s and t-channel helicity distributions. A two component model is proposed, the predictions of which are in good agreement with our data.",

note = "Funding Information: In this paper we discuss some of the results of our study of rrp -\textasciitilde{} rr(Nzr) reactions at 3.9 GeV/c and propose a model which explains three puzzling features of these data. The first of these is the observation that there are low mass enhancements observed in the amplitudes obtained from a cross channel analysis of the 1 = ½ (Nrr) final state. The second is the result that the individual cross sections for the four diffraction dissociation (dd) channels, zrp \textasciitilde{} rr(Nlr)dd, are in apparent disagreement with the ratios predicted by iso. spin invariance. The third is the observation of s and t channel helicity non-conservation in these diffraction dissociation channels. We have been able to explain these features in terms of a two component model and find that its other predictions are in good agreement with our data. This model assumes that two types of production amplitudes are important in the zrp \textasciitilde{} rr (Nrr) reactions, the single exchange and double exchange amplitudes depicted in fig. 1. The properties of both the single exchange amplitude \textbackslash{}[1\textbackslash{} ] and the double exchange amplidtude have been discussed previously \textbackslash{}[2-5\textbackslash{}]. The first portion of our data that we wish to discuss is the results of our cross channel isospin analysis \textbackslash{}[6\textbackslash{}]u sing the expressions given by Koba et al. \textbackslash{}[7\textbackslash{}].I n this analysis it is assumed that the cross sections may This work is supported in part through funds provided by the Atomic Energy Commission under Contract No. AT (11-1) 3069.
