Abstract

Hadronic mass spectra are systematically fitted to a QCD and bag motivated expression in which the quark interaction matrix elements are allowed to assume best values. A statistically significant fit is found with B 1 4 ≈ 170 MeV. The inclusion of surface energy σ has been studied and we have found a second, equally significant fit with B 1 4 ≈ 210 MeV and σ ≈ 40 MeV/fm2. However, the corresponding hadrons are unacceptably small, i.e. R ≈ 0.5 fm. Selected strange multiquark states are recomputed and found to have generally a higher mass than currently believed.
