The Body Center Cubic Quark Lattice Model (A Modification and Further   Development of the Quark Model)
  We assume that the u quarks and the d quarks constitute a body center cubic quark lattice in the vacuum. Using energy band theory, we deduce an excited quark spectrum (from the quark lattice). Using the accompanying excitation concept, we deduce a baryon spectrum (including S, C, b, I, Q, and mass) from the quark spectrum. With a phenomenological binding energy formula, we deduce a meson spectrum (including S, C, b, I, Q, and mass) from the quark spectrum. The baryon and meson spectra agree well with experimental results. The BCC Quark Model predicts many new quarks (u'(3), d'(6)), baryons ($\Lambda^0(4280)$, $\Lambda_{C}^{+}(6600)$, $\Lambda_{b}^{0}(9960))$, and mesons (K(3597), D(5996), B(9504), $\eta(5926)$, $\Upsilon(17805)$, T(1603) with I=2). The quarks u'(3) and d'(6) and the meson T(1603) have already been discovered.
