Abstract

We 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 ηb meson to have mass near 9400 MeV .
