Self-consistent light-quark qqq and qqq-bar q-bar mass spectrum

Recently, an improved approximate self-consistent dual-topological-unitarization technique has been developed, in which the effect of planar sea-quark loops is taken into account from the beginning. This is applied to qqq and qqq-bar q-bar hadrons with q = u,d,s, and good agreement is obtained with experiment. In particular, we predict 2/sup -/ and 3/sup +/ ..lambda..p-bar states, which can be identified with recently observed broad resonances of mass 2.20 and 2.33 GeV.
