Baryon Number (BN) is associated with a specific topology of gluonic fields, rather than with the valence quarks. The BN is frequently confused with the difference between the quark and antiquark distributions in the hadron. However, that they have quite different x-dependences. The BN asymmetry distribution is nearly constant at small x, while valence $q(x)-\bar q(x) \propto \sqrt{x}$. The...
