The nuclear binding and the EMC effect in the deuteron

چکیده

Influence of the nuclear binding in the deuteron deep inelastic structure function F2(x,Q 2) is investigated. The description is based on the Bethe-Salpeter formalism in the ladder approximation and the operator product expansion within an effective mesonnucleon theory. It is shown that the binding in a fully relativistic treatment can be simply parametrised and its origin can be understood in terms of conventional nuclear degrees of freedom. A numerical estimate of the EMC effect in the deuteron is given.

Relativistic nature of the EMC-effect

The deep inelastic scattering of leptons off nuclei is studied within the the BetheSalpeter formalism. It is shown that nuclear short-range structure can be expressed in terms of the nucleon structure functions and four-dimensional Fermi motion of the nucleons. The four-dimensional Fermi motion broadens the bound nucleon localization area, what leads to the observation of the nucleon structure ...

Detailed studies of the nuclear dependence of F 2 in light nuclei

We propose to perform inclusive electron scattering measurements from several light to medium heavy nuclei over a broad range of x (0.1 < x < 1) up to Q ≈ 15 GeV. These data will improve on existing JLab measurements of the EMC effect by extending precise extraction of the EMC ratios to larger x values, and by making additional measurements on light nuclei (A < 12) to provide better data for co...

Probing the Origin of the EMC Effect via Tagged Structure Functions of the Deuteron

We demonstrate that measurement of tagged structure functions of the deuteron in (e, eN) semi-inclusive reactions can discriminate between different hypotheses on the origin of the nuclear EMC effect. By choosing extreme backward kinematics for the spectator nucleon to minimize effects from the deuteron wave function and final state interactions, one can isolate the modifications in the structu...

روش خودسازگار در محاسبه نسبت با استفاده از تابع ساختار و نسبت EMC هسته‌های He3 و H3

By using the convolution formalism which consists of Fermi motion and binding effect, we investigate the deep inelastic electron scattering from A=3 mirror in the deep-valence region. The initial valence quark input is taken from the GRVs (Gluck, Reya and Vogt) fitting procedure and the next-to-leading order QCD evolution on FP2 (x,Q2) which gives very good fit to the available data in the (x,Q...

Evolution of the EMC Effect in Light Nuclei

The evolution of the EMC effect as a function of atomic mass A is considered for the first time for the lightest nuclei, D, 3 H, 3 He and 4 He, with an approach based on the Bethe-Salpeter formalism. We show that the pattern of the oscillation of the ratio r A (x) = F A 2 /F N(D) 2 varies with A, unlike the pattern for nuclei with masses A > 4, where only the amplitude of the oscillation change...
