  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.
