Fast-hadron formation mechanism in leptoproduction in nuclei

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The mechanism of fast-hadron leptoproduction in nuclei in deep inelastic region is considered. Different possible mechansims of fast-hadron formation in the virtual-photon fragmentation region and the process of transition of the quark (quark-gluon system) through nuclear matter is analysed. The “range of consistency” of the SLAC and EMC CERN data on meson leptoproduction in different nuclei is obtained to be 0.2 GeV2≤m 2c ≤0.5 GeV2. It is shown that the kinematic region 0.05≤x B ≤0.3 and (3–5)≤Q 2/m 2c ≤100 is the most favourable for an investigation of the growth law (evolution) of the transverse dimensions of quark (quark-gluon system) produced by the virtual photon.
