Abstract
We show that, in the Regge limit, beam asymmetries in eta and eta' photoproduction are sensitive to hidden strangeness components. Under reasonable assumptions about the couplings we estimate the contribution of the phi Regge pole, which is expected to be the dominant hidden strangeness contribution. The ratio of the asymmetries in eta' and eta production is estimated to be close to unity in the forward region 0 < -t/GeV2 <= 1 at the photon energy E-lab = 9 GeV, relevant for the upcoming measurements at Jefferson Lab.
