If, as is commonly accepted, the colour-singlet, `preconfined', perturbativeclusters are the primary units of hadronization, then the electric charge isnecessarily compensated locally at the scale of the typical cluster mass. As aresult, the minijet electric charge is suppressed at scales that are greaterthan the cluster mass. We hence argue, and demonstrate by means of Monte Carlosimulations using HERWIG, that the scale at which charge compensation isviolated is close to the mass of the clusters involved in hadronization, andits measurement would provide a clue to resolving the nature of the dynamics.We repeat the calculation using PYTHIA and find that the numbers produced bythe two generators are similar. The cluster mass distribution is sensitive tosoft emission that is considered unresolved in the parton shower phase. Wediscuss how the description of the splitting of large clusters in terms ofunresolved emission modifies the algorithm of HERWIG, and relate the findingsto the yet unknown underlying nonperturbative mechanism. In particular, wepropose a form of $\alpha_S$ that follows from a power-enhanced beta function,and discuss how this $\alpha_S$ that governs unresolved emission may be relatedto power corrections. Our findings are in agreement with experimental data.Comment: 37 pages, 20 figure
