Abstract
A theoretical model is presented to describe the angular correlations and differential cross-section for the reaction π+N→ϱ+N*, where the ρ andN* decay into two pions, and into pion+nucleon, respectively. For the production mechanism a Regge-pole model is assumed involving the exchange of the π and A2 trajectories; while the A2 is fully Reggeized, arguments are presented in favour of treating the pion essentially as elementary. Assuming that thet-dependence of the residue functions is given by the kinematic singularities and zeros, together with an exponential behaviour which is independent of the helicities, the number of parameters required can be reduced to seven. For the purpose of the experimental analysis (which will be carried out in a subsequent paper) a list of projection functions is given, with the help of which the various coefficients multiplying the angular functions describing the decay distribution may be obtained.
