Title: Finite-energy sum rules in eta photoproduction off a nucleon

Abstract

The reaction $${\gamma}N \to {\eta}N$$ is studied in the high-energy regime (with photon lab energies $$E_{\gamma}^{\textrm{lab}} > 4$$ GeV) using information from the resonance region through the use of finite-energy sum rules (FESR). We illustrate how analyticity allows one to map the t-dependence of the unknown Regge residue functions. As a result, we provide predictions for the energy dependence of the beam asymmetry at high energies.
