Abstract
Deep inelastic scattering (DIS) events, selected from 1993 data taken by the H1 experiment at HERA, are studied in the Breit frame of reference. The fragmentation function of the quark is compared with those of e+e− data. It is shown that certain aspects of the quarks emerging from within the proton in e−p interactions are essentially the same as those of quarks pair-created from the vacuum in e+e− annihilation. The measured area, peak position and width of the fragmentation function show that the kinematic evolution variable, equivalent to the e+e− squared centre of mass energy, is in the Breit frame the invariant square of the four-momentum transfer. We comment on the extent to which we have evidence for coherence effects in pArton showers.
