Title: Neutral pion photoproduction in a Regge model

The reaction $$\gamma p \to \pi^0 p$$ is investigated in the energy range above the resonance region. The amplitudes include the leading Regge singularities in the cross-channel and correctly describe the differential cross section for beam energies above 4 GeV and for momentum transferred above $$-3\mbox{ GeV}^2$$. Furthermore, the energy dependence of the beam asymmetry and the reaction $$\gamma n \to \pi^0 n$$ seem is quantitative consistent with the Regge-pole dominance.
