Proton-antiproton annihilation into a Lambda_{c}^{+} bar{{Lambda}}_{c}^{-} pair

The process p $ bar{{p}}$ $ rightarrow$ $ Lambda_{c}^{+}$ $ bar{{Lambda}}_{c}^{-}$ is investigated within the handbag approach. It is shown to lowest order of perturbative QCD that, under the assumption of restricted parton virtualities and transverse momenta, the dominant dynamical mechanism, characterized by the partonic subprocess u $ bar{{u}}$ $ rightarrow$ c $ bar{{c}}$ , factorizes in the sense that only the subprocess contains highly virtual partons, namely a gluon, while the hadronic matrix elements embody only soft scales and can be parameterized in terms of helicity flip and non-flip generalized parton distributions. Modelling the latter functions by overlaps of light-cone wave functions for the involved baryons we are able to predict cross-sections and spin correlation parameters for the process of interest.
