New meson configurations in the bag model. II. Mixing effects

Abstract

For pt.I see ibid., vol.185B, no.2, p.391-402 (1981). The author evaluates transitions and mixings between ordinary mesons, glueballs, multiquark states, and unconventional quark-antiquark-gluon configurations (hybrid states). Hybrid states mix largely with qq macr , glueballs contain some component of qq macr g (but nearly none of qq macr ), whereas the multiquarks are nearly disconnected. Based on a naive perturbative estimate, the author expects hybrid states to be large and lowest glueballs to form narrow resonances.Anglai
