23 Apr 2013 | Abstract: | The associated production of a J/{psi} and a pi-meson in antiproton-nucleon
annihilation is studied in the framework of QCD collinear factorization. In
this approach, a hard subprocess responsible for the production of the heavy
quark-antiquark pair factorizes from soft hadronic matrix elements, such as the
antiproton (nucleon) distribution amplitude and the nucleon-to-pion
(antiproton-to-pion) transition distribution amplitude. This reaction mechanism
should dominate the forward and backward kinematical regions, where the cross
sections are expected to be measurable in the set-up of the PANDA experiment at
the GSI-Fair facility. | Source: | arXiv, 1304.6298 | Services: | Forum | Review | PDF | Favorites |
