Abstract
An inclusive determination of the (Γ/M) ratios of mesons and baryons is made from the ansatz that there exists a short breathing mode for the temporary dissociation of a hadron into a pair of “quasifree” quarks (q) and/or diquarks (D) with significantly lower masses than their constituent values which subsequently hadronize with certainty. The coupling scheme for mesons to these [Formula: see text] and DD* pairs (which yields Γ directly) is determined by Schwinger’s partial symmetry for quarks (which “subsumes” the Sakurai gauge principle for ρ, ω, ɸ couplings to [Formula: see text] pairs). A similar construction holds for baryon couplings to quark(q)-diquark(D) pairs, with the same overall coupling constant(gs) for both systems. Its tentative identification with the QCD value yields a surprisingly good pattern of agreement with data for both hadron types, using just two inputs (mud and ms). The Γ/M ratios (R) are expressible as αs(M2) f(J, M/mq), and indicate discreteness in R iff the standard Regge slope patterns in M2 are taken into account.
