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