“…However, there is no unique model, and since none of the models covers reliably the whole x-range, we do not want to stick to any particular model at this point, but rather try to see what could be inferred directly from the measured data. Therefore, we first parametrize the deep inelastic lepton-nucleus data of NMC [14] and SLAC [10] for the F 2 -ratio (see fig. 1) in the somewhat complicated form described in Appendix.…”

“…According to the measurements of the ratio ~ Fl I !FP there is a clear depletion from unity at x ;S ,0.1 (shadowing) [12][13][14], and at 0.3 ;S x ;S 0.7 (EMC-effect) [S-13]. An increase in this ratio occurs at 0.1 ;S x ;S 0.3 (antishadowing) and at 0.S5 ;S x ;S 1 (Fermi motion) [10,13].…”

“…In section 2 we describe how we incorporate the NMC and SLAC deep inelastic lepton-nucleus data for ~ Fl I !FP [14,10], the E772 data for dilepton production [17] in pA vs. pD collisions and the baryon charge conservation sum rule to determine the valence and sea quark distributions in nuclei at an initial scale Qo = 2 GeV, motivated by the analysis of ref.

“…In deeply inelastic lepton-nucleus scattering experiments it has been observed that there are significant nuclear modifications to the distributions of quarks and antiquarks in free nucleons [8][9][10][11][12][13][14]. This means that parton distributions in a nucleus A are not simply given by Ii/A(X, Q2) = AIi/N(X, Q2), where Ii/N(X, Q2) is the probability of finding a parton i with a momentum fraction x of the momentum of the nucleon N. The scale Q is the momentum scale up to which the parton has QCD-evolved.…”

I n this paper we discuss in detail the hyothesis that nuclei show extended quark and gluon modes when explored with a high resolution probe. We call this color conductivity a t high resolution. We relate color conductivity to the behaviour of proton-proton total and elastic cross sections a t high energies. For deep inelastic muon-nucleon scattering we discuss in detail the nuclear evolution equation following from color conductivity and introduced by us previously. The EMC Fe/d data are well described by our theory if due allowance is made for the quoted systematic error. We predict striking effects from color conductivity in the final state of deep inelastic lepton-nucleus scattering. The possibility of making fundamental tests of quantum ohromodynamics in leptonnucleus scattering is emphasized. We connect the shadowing phenomenon to the volume and surface terms in the Bethe-Weizsacker formula for the nuclear binding energy. Finally we point out that deep inelastic scattering on deformed nuclei may be crucial to distinguish between different theories of the EMC effect. Farbleitung bei Hochauflosung : Ein neues Phiinomen der KernphysikInhaltsubersicht. I n dieser Arbeit diskutieren wir detailliert die Hypothese, daB Kerne bei hochauflosender Untersuchung ausgedehnte Quark-und Gluonenmoden zeigen. Wir korrelieren die Farbleitung mit dem Verhalten von totalem und elastischem Proton-Proton-Wechselwirkungsquerschnitt bei hohen Energien. Fiir tief inelastische Myon-Nukleonstreuung diskutieren wir im Detail die von uns fruher eingefuhrte, aus der Farbleitung folgende Entwicklungsgleichung der Kerne. Die EMC Fe/d-Werte werden durch unsere Theorie im Rahmen des berichteten systematischen Fehlers gut beschrieben. Wir sagen auffallende Effekte im Endzustand der tief inelastischen Leptonen-Kern-Streuung, die aus der Farbleitung folgen, voraus. Die Moglichkeit fundamentaler Tests der Quantenchromodynamik bei Leptonen-Kernstreuung wird unterstrichen. Wir verbinden das Schattenphanomen mit Volumen-und Oberflachentermen in der Bethe-Weizsacker Formel fur die Kernbindungsenergie. AbschlieBend weisen wir darauf hin, daB die tief inelastische Streuung an deformierten Kernen kritisch fur die Entscheidung zwischen den verschiedenen Theorien des EMC-Effektes sein konnte.

The present situation in deep inelastic lepton-nucleon scattering is reviewed from an experimenter's point of view . After describing. in some detail. the quark-parton model (QPM) predictions the basic ideas of Quantum Chromodynamics (QCD) are illustrated . The perturbative QCD predictions for deep inelastic scattering are summarised discussing also their theoretical uncertainties of today .Past and present experiments on deep inelastic electron and muon scattering are compared regarding their ability to test these predictions . It is shown that all data is in very good agreement with the QPM and fully consistent with perturbative QCD . New results on lepton scattering off nuclei are discussed and confronted to recently invented phenomenological models .
