IV.D200 — Meson classification

A meson |q_i q_bar_j> is classified by three attributes: flavor content (quark flavors from {u,d,s,c,b,t}), spin-parity J^PC (from orbital and spin angular momentum), and generation class (lemniscate mode classes of constituent quarks); pseudoscalar (J=0) and vector (J=1) mesons correspond to anti-aligned and aligned spins.
