Some applications of isospin relations of inclusive reactions

The isospin equalities of inclusive cross-sections are combined with the Mueller formalism to obtain relations of fragmentation and pionization vertices and useful simplified relations of inclusive cross-sections. Isospin equalities of two-particle correlation functions are derived for particles of various isospins with the produced particles in the fragmentation region, or one in the fragmentation region and the other in the pionization region, or both in the pionization region.
