Abstract

We calculate the amplitude for exclusive electroweak production of a pseudoscalar D_s or a vector D^*_s charmed strange meson on an unpolarized nucleon, through a charged current, in leading order in α_s. We work in the framework of the collinear QCD approach where generalized gluon distributions factorize from perturbatively calculable coefficient functions. We include both O(m_c) terms in the coefficient functions and O(M_D) mass term contributions in the heavy meson distribution amplitudes. We show that this process may be accessed at future electron-ion colliders.
