    • In the search for heavy, narrow exotic states such as baryonium or glueballs, carried out so far, various methods of high- and low-energy production, low-energy formation, and e+e- reactions were used. In particular, a search for baryonium states below threshold (mxlsimmppmacr) has shown some evidence [Richter et al., 1983, Brando et al., 1984] for a few states. However, the results of these measurements suffer from poor statistics. Among the possible methods which can be applied in the baryonium bound state research at LEAR, the authors consider the study of the reaction ppmacrrarrX+pi0 as the most promising. They have performed an experiment to study this reaction by means of an experimental set-up especially tailored for measuring monoenergetic pi0,s, allowing for both angular distribution measurements and high-resolution spectroscopy. They report on the preliminary results from our actual measurements of the inclusive pi0 and eta spectra following the antiproton annihilation at rest.

  • Conference paper (peer-reviewed)abstract
    • Various theoretical ideas on nuclear physics, quark models, and the dual topological unitarization lead to the expectation of massive mesons, called baryonium, coupled strongly to the ppmacr channel but weakly to mesons, thus resulting in a virtually high stability, particularly below the ppmacr threshold. Such states are relevant to nuclear physics owing to the fact that the badly explored short-range forces in the NN interactions are just the most relevant ones in the NNmacr systems. From the known NN potential, one is led to expect short-range attraction in NNmacr systems, and this should result in quasinuclear bound states in the vicinity of threshold.
