Hadron formation and attenuation in deep inelastic lepton scattering off nuclei
نویسنده
چکیده
We investigate hadron formation in deep inelastic lepton scattering on N , Kr and Xe nuclei in the kinematic regime of the HERMES experiment. The elementary electron-nucleon interaction is described within the event generator PYTHIA while a full coupled-channel treatment of the final state interactions is included by means of a BUU transport model. We find a good agreement with the measured charged hadron multiplicity ratio Rh M for N and Kr targets by accounting for the deceleration and absorption of the primarily produced particles as well as for the creation of secondary hadrons in the final state interactions.

High energy electroproduction off complex nuclei
We investigate hadron attenuation in deep-inelastic lepton scattering off complex nuclei in the kinematic regime of the HERMES experiment. Our transport theoretical simulations reveal strong prehadronic final state interactions of the reaction products with the surrounding nuclear medium early after the initial γ∗N interaction has taken place. In this work we compare our model results with the ...
متن کاملAtomic Mass Dependence of Hadron Production in Deep Inelastic Scattering on Nuclei
Hadron production in lepton-nucleus deep inelastic scattering is studied in an absorption model. In the proposed model, the early stage of hadronization in the nuclear medium is dominated by prehadron formation and absorption, controlled by flavor-dependent formation lengths and absorption cross sections. Computations for hadron multiplicity ratios are presented and compared with the HERMES exp...

متن کاملConfinement and the Transverse Lattice∗
Deep inelastic lepton-hadron scattering has played a fundamental role in the investigation of hadron structure. For example, the discovery of Bjorken scaling confirmed the existence of point-like charged objects inside the nucleon (quarks). Besides such fundamental discoveries, deep inelastic scattering (DIS) revealed surprising and interesting details about the structure of nucleons and nuclei...
متن کاملHadron production in deep inelastic lepton-nucleus scattering
Predictions for semi-inclusive deep inelastic lepton-nucleus scattering are presented. Both the effects of gluon radiation by the struck quark and the absorption of the produced hadron are considered. The gluon radiation covers a larger window in virtuality Q2 because of the increased deconfinement of quarks inside nuclei. The absorption of hadrons formed inside the nucleus is described with a ...
