AB 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 eta(b) meson to have mass near 9400 MeV.© Springer-Verlag / Societa` Italiana di Fisica 2003.This work was supported by Spanish grants FPA 2000- 0956, BFM 2002-01003 (F.L-E.) and the U.
