PERTURBATIVE versus NONPERTURBATIVE SCALING VIOLATION IN QUARK FRAGMENTATION

We investigate the approach to scaling for non-perturbative quark fragmentation in the frame-work of the uncorrelated jet model. It is found that subasymptotic kinematic scale breaking is comparable in size to scaling violations from hard gluon emission a la QCD. Experimental data available at present do allow for such non-perturbative scale breaking effects.
