Abstract Assuming that the Bardakçi-RueggB 5-function is relevant for the dynamical description of hadronic single particle production processes we construct a model for the π π π $${\cal N}\bar {\cal N}$$ -five-point function. For the invariant functions appearing in a suitably chosen invariant decomposition an ansatz is made in terms ofB 5-functions multiplied by polynomials of the invariant variables which are required by factorization. The Regge trajectories introduced are those of the π, ϱ,P′, ω and $$\mathcal{N}$$ . With this set of trajectories, admitting as small a number of satellite terms as possible, invariant functions are constructed having both the correct crossing and factorization properties at the π, $$\mathcal{N}$$ (and $$\bar {\cal N}$$ ) poles. Further constraints emerge from an investigation of the asymptotic behaviour in the single Regge limits. Only one parameter remains undetermined. As an application of the model consequences for the process $$\pi \mathcal{N} \to \rho \mathcal{N}$$ are studied.
