Production of heavy meson pairs in p pbar collisions within a double handbag approach

Résumé

We study the pair-production of heavy mesons in proton-antiproton annihilations within a perturbative QCD-motivated framework. In particular we investigate p pbar ->Dbar 0 D0 within a double handbag approach, where a hard subprocess factorizes from soft hadronic matrix elements. The soft matrix elements can be parametrized by transition distribution amplitudes, which are off-diagonal in flavor space. The transition distribution amplitudes are modelled as overlaps of light-cone wave functions. We obtain rather robust model results for p pbar -> Dbar0 D0 cross sections, which are expected to be measured at the future PANDA detector at GSI-FAIR.
