A search for resonances in the antiproton-proton system at low energies
Description
The excitation function of the annihilation and elastic cross-sections for the antiproton-proton scattering have been measured in the mass range from 1910 to 1978 MeV. The experiment was characterized by a mass resolution of about 0.4 MeV (R.M.S.) and a statistical significance of 1.2% (R.M.S.) for the annihilation channel. With this precision a narrow structure at a mass of 1936 MeV was observed. This structure is not of a simple Breit-Wigner shape. However, it might be identified with the S-meson reported by a previous experiment. (orig.)
