On the η and η′ photoproduction beam asymmetry at high energies
We show that, in the Regge limit, beam asymmetries in η and η′ photoproduction are sensitive to hidden strangeness components. Under reasonable assumptions about the couplings we estimate the contribution of the ϕ Regge pole, which is expected to be the dominant hidden strangeness contribution. The...
