Abstract
A fit of forward charged-pion photoproduction data is attempted by parametrizing Regge pole-cut combinations in the region $t<0$ in terms of complex conjugate pairs of Regge poles. In particular, the pion-Pomeranchukon cut is taken into account by this parametrization; in addition to the pion, exchange of the ${A}_{2}$ meson is considered. Predictions are made for the differential cross section and the asymmetry parameters for pion production by linearly polarized photons and polarized target nucleons. The results are found to be in good agreement with pion photoproduction data for laboratory photon energies ranging from 3.4 to 18 GeV and $t$ values up to -0.2 ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$.
