The process is described by a handbag-type mechanism with the charm-quark mass acting as the hard scale. As in the case of preceding work on $\\bar{p}  p \\rightarrow \\bar{\\Lambda}^-_c  \\Lambda_{c}^{+} $ we argue that the process amplitude factorizes into one for the perturbatively calculable partonic subprocess $\\bar{u} u\\rightarrow \\bar{c} c$ and hadronic matrix elements that can be parameterized in terms of generalized parton distributions.
