Description
In the experiment carried out by the BIS-2 collaboration at the Serpukhov accelerator the search has been performed for baryonium with hidden strangeness, decay products of which are containing baryon-antibaryon pair, and also particles with opposite strangenesses. In eight different invariant mass spectra of the neutral and charged final states, the narrow peaks are observed at one and the same mass value. This indicates the existence of the nonstrange baryonium in three charged states: +1,0 and -1. The mass of the resonance is equal to 3255±10 (stat.)±30(syst.) MeV/c2. The width of the resonance does not exceed 30 MeV/c2
