Abstract
- The recently discovered Z(4430) mesonic resonance is believed to be a strong tetraquark candidate. The photoproduction in the channel γp → Z+(4430)n → ψ′π+n has been proposed as the most effective way to confirm the Z(4430) presence and to measure its quantum numbers. In this work we present a model for high-energy and forward-angle Z(4430) photoproduction in a effective Lagrangian approach. This model is based on the use of Regge trajectories exchange, thus a Regge propagator replaces the usual Feynman propagator. The differential and total cross sections and the asymmetries have been calculated for the JP quantum numbers 1-, 1+, 0-, and 2- in the hypotheses where Z(4430) has isospin I = 1.
