Abstract
We examine the hadronization process in QCD, modeling it as a series of independent parton-meson scatterings. In the limit of rapid scatterings, obtained by neglecting mass terms, we find a simple description of the hadronizing system. The consequences of this description, and the effects of heavy quarks, are discussed.

- Actually, in some cases the vacuum need not be trivial due to the existence of dynamical ``zero modes,'' which correspond to fluctuations with =0 in the initial-state boundary conditions. For a review see, for example, S. J. Brodsky et al., Part. World 3, 109 (1993).
- We can phrase the same assumption somewhat differently in the language of the Kinoshita-Lee-Nauenberg theorem. To wit, we assume that the actual eigenstates of the Hamiltonian that governs hadronization, while they freely mingle parton and hadron states, have a well-defined total particle multiplicty N.
