Rules for combinations Baryon: 3 quarksMeson: 2 quarks(1 quark + 1 anti-quark) No fractional charges in completed particle • Proton • Neutron • Anti-proton • Anti-neutron • Hydrogen atom • Helium nucleus • Helium atom
Baryons (3 quarks) Σ+ charge, Q = +1 strangeness, S = -1 Neutron charge, Q = 0 strangeness, S = 0 n Σ +
Mesons (1 quark + 1 anti-quark = 2 quarks)
