Charged current electroproduction of a charmed meson at an electron-ion collider

We calculate the amplitude for exclusive electroweak production of a pseudoscalar Ds or a vector D = s charmed strange meson on an unpolarized nucleon, through a charged current, in leading order in alpha s. We work in the framework of the collinear QCD approach where generalized gluon distributions factorize from perturbatively calculable coefficient functions. We include both Oomc thorn terms in the coefficient functions and OoMD thorn mass term contributions in the heavy meson distribution amplitudes. We show that this process may be accessed at future electron-ion colliders.

Automated summary

In this study, we calculated the amplitude for exclusive electroweak production of pseudoscalar Ds or vector Ds charmed strange meson on an unpolarized nucleon in leading order alpha s. We utilized the collinear QCD approach where generalized gluon distributions factorize from perturbatively calculable coefficient functions. It was shown that this process could potentially be studied at future electron-ion colliders.
