✦ Synopsis

An investigation

of the mass levels of ground and excited qq@ (baryonium) states is carried out within a Bethe-Salpeter framework for a four-body system with pairwise q-4 and q-q interactions of the h.o. type. The identity of quarks, and separately, of antiquarks, in a qq@ system gives rise to a well-defined set of selection rules governing the spin-isospinorbital structures of T-and M-baryonia. A relativistic mass formula, similar to those derived recently for q4 and qqq systems, including spin and momentum dependent effects, is now obtained for the qqqq system. The values of the parameters employed for mass prediction for
