Fig.1A. The masses of common Standard Model hadron particles are graphed against the sums of the separate individual masses of the 2 or 3 component quark class (q) particles, quarks or anti-quarks, for each case. Circles indicate neutral particles;minuses and pluses indicate charges. Anti-particles may be overlaid. Including the neutron (n) and the proton (p), particles are indicated by the Greek and English letters as a common form of their names.
