The Regge-pole formalism is applied to the calculation of the differential cross section for A1+ photo-production in the region |tmin| < -t < 10µ2. The p, A1, A1-daughter, A2, and π trajectory contributions are considered, and use is made of chiral dynamics to estimate the unknown coupling constants. We find that the π and the A2 trajectories provide the dominant contributions.
