Assuming dominance by a single scalar state, as suggested by a phase-shift analysis, we find a mixing angle $γ\sim 36^{\circ}$, corresponding to near-maximal mixing of the glueball and $\bar{s}s$ components.7 pages, LaTeXHigh Energy Physics - PhenomenologyScalar Glueball--Quarkonium Mixing and the Structure of the QCD Vacuumtext
