$\pi \eta$ pair hard electroproduction and exotic hybrid mesons

Abstract

We show that hard electroproduction is a promising way to study exotic hybrid mesons, in particular through the hybrid decay channel $H\to \pi \eta$. We discuss the $\pi \eta$ generalized distribution amplitude, calculate the production amplitude and propose a forward-backward asymmetry as a signal for the hybrid meson production.
