Title: Baryon-antibaryon decays of four-quark states

Baryon-antibaryon decays of four-quark states We classify all the SU(3) multiplets of {ital T}-diquonia consistent with the Pauli principle, and estimate their masses using a potential model. Within the framework of the {sup 3}P{sub 0} model, we calculate the total and partial decay widths of these states into baryon-antibaryon pairs. We find that both the total widths and the partial widths range from a few MeV to several hundred MeV. We briefly discuss implications for experimental detection of diquonia.
