Psi to N Nbar m
In this invited talk I discuss two recent applications of charmonium (Psi)
decays to N Nbar m final states, where N is a nucleon and m is a light meson.
There are several motivations for studying these decays: 1) They are useful for
the study of N* spectroscopy; 2) they can be used to estimate cross sections
for the associated charmonium production processes p pbar to Psi m, which PANDA
plans to exploit in searches for charmonium hybrid exotics; and 3) they may
allow the direct experimental measurement of NNm (meson-nucleon) strong
couplings, which provide crucial input information for meson exchange models of
the NN force. The latter two topics are considered in this talk, which will
also compare results from a simple hadron pole model of these decays to recent
experimental data.Comment: Invited contribution to Charm2010 (Fourth International Workshop on
