Regge description of two pseudoscalar meson production in antiproton-proton annihilation
Résumé
A Regge-inspired model is used to discuss the hard exclusive two-body hadronic reactions ( $ \bar{{p}}$ p $ \rightarrow$ $ \pi^{-}_{}$ $ \pi^{+}_{}$ , $ \pi^{0}_{}$ $ \pi^{0}_{}$ , K - K + , $ \overline{{K}}^{{_{{ \scriptstyle 0}}}}_{}$ K 0 for the FAIR facility project at GSI with the PANDA detector. The comparison between the differential cross-sections predictions and the available data is shown to determine the values of the few parameters of the model.
