Consequences of Internal Symmetries for Inclusive Processes

Consequences of $C$ invariance, isospin invariance, and unitary symmetry for limiting distributions are derived. The same symmetries are used to isolate the nonscaling contributions. Many of the predictions are susceptible to direct experimental test. The relations based on unitary symmetry are expected to be violated and thus furnish extensive challenges to symmetry-breaking models. The relations based on isospin and $C$ invariance are expected to be exact (asymptotically) at high energies.
