| Abstract: | In a search for glueballs and exotic states decaying into baryons and antibaryons we have investigated the production of baryon antibaryon pairs produced centrally in the reactions π+/pp → π+/p(X 0)p at 85 GeV/c. In particular, channels whereX 0 goes to \(p\bar p,p\bar p\pi ^ + \pi ^ - ,p\bar p2\pi ^ + 2\pi ^ - \) and \(\Lambda \bar \Lambda \) have been observed. No significant new structure is observed in the mass spectra. |
