Charge Transfer in High-Energy Fragmentation

Nontransference of charge is an essential aspect of the hypothesis of limiting fragmentation for infinite-energy hadron-hadron collisions. One can define experimentally a charge transfer $u$ from one c.m. momentum-space hemisphere to another. At finite energies, $u$ is not zero because the fragments may "spill over" to the other hemisphere. A model is discussed which yields an estimate of $u$. The general validity of the energy and multiplicity dependence of this estimate is then commented upon.
