Internal Symmetries and Model-Independent Relations for Inclusive Processes

Phys. Rev. Lett. 28, 862 – Published 27 March 1972

Symmetries restrict isospin and SU(3) dependence of single-particle and multiparticle inclusive and semi-inclusive cross sections. Isospin relations test treatments of experimental data, including deuteron corrections, Λ-Σ0 separations, and resonance-background separations. They also test the isospin structure of initial states in photoproduction, electroproduction, and neutrino-production processes; and they can reveal Coulomb effects in p¯d or p¯α annihilation. Applied separately to beam and target fragments, they test diffractive excitation models.
