Relations of Particle Quantum Numbers and Variations of the Numbers in a Particle Reaction
Zhang Mou-zhen · 1999
The relation of hadron spin to its electric charge and baryon number is induced from the known facts. From it and Gell Mann Nishijima relation, the relation between spin and isospin, baryon numbre, strangeness, charm and bottom is derived. When isospin for hadrons is directly extended to leptons, the relations of leptons similar to the ones of hadrons are found. From them, three common relations for both leptons and hadrons are further induced. On the basis of the common ones, variation rules of the quantum mumber in particle reactions are derived.
