Abstract: The QCD collinear factorization framework allows one to describe exclusive backward production of a $J/\ensuremath{\psi}$ meson in pion-nucleon collisions in terms of pion-to-nucleon transition distribution amplitudes. We calculate the scattering amplitude at the leading order… read more here.
