Summary
We briefly review theoretical calculations for the pseudoscalar-vector meson hyperfine splitting with no open flavor and also report a many body field theoretical effort to assess the impact of chiral symmetry in the choice of effective potentials for relativistic quark models. Our calculations predict the missing eta{sub b} meson to have mass near 9400 MeV. The radial excitation η{sub c}(2S) is in agreement with the measurements of the BELLE and most recently BABAR collaborations.
