The Nature of Nonperturbative Effects in Lepton-nucleon Scattering*
نویسنده
چکیده
There is evidence for substantial nonperturbative effects in the structure functions extracted from deep-inelastic lepton-nucleon scattering. These effects have a major impact on us and A determinations. Results which I reported previously for pN and vN scattering (Fz and xF3) are extended to include ed data which are at lower W2 and higher x and have extremely high statistics. Possible analytical forms for higher-twist terms and for a, are considered in detail here using (rN, vN and ed data.

In this paper, we calculate nuclear structure function and EMC effect of 40Ca and 56Fe nuclei. To achive the goals, we consider Fermi motion and binding energy contrbiution in the harmonic oscillator model. In this model, harmonic oscillator parameter ħω related to shells root mean square radius and for free nucleon structure functions, is obtained from GRV’s free nucleon structure functions. ...

Information obtained from nucleus as a bound system of nucleons and from nucleon-nucleon scattering experiments is a strong tool for studying various aspects of nuclear forces. Deuteron-deuteron scattering as a four-nucleon system can provide useful information. So, scattering experiment of a polarized beam of deuteron with kinetic energy of65 MeV/nucleon from a liquid-deuterium target was done...
متن کاملNucleon-Nucleon Correlations and Six-Quark Cluster Effects in Semi-Inclusive Deep Inelastic Lepton Scattering off Few-Nucleon Systems
Semi-inclusive deep inelastic lepton scattering off few-nucleon systems is investigated assuming that virtual boson absorption occurs on a hadronic cluster which can be either a two-nucleon correlated pair or a six-quark bag. In both cases the relevance of nuclear effects on forward and backward nucleon emissions is illustrated and the differences expected in the energy distribution of the emit...
متن کاملRenormalization of EFT for nucleon-nucleon scattering
The renormalization of EFT for nucleon-nucleon scattering in nonperturbative regimes is investigated in a compact parametrization of the T -matrix. The key difference between perturbative and nonperturbative renormalization is clarified. The underlying theory perspective and the ’fixing’ of the prescriptions for the T -matrix from physical boundary conditions are stressed.

We predict the triple differential cross section of the unpolarized Drell-Yan process at √ S = 6 GeV. The model incorporates primordial parton transverse momentum and quark off-shellness effects caused by the initial state interaction. The study of the Drell-Yan lepton pair production process (NN → µ + µ − X) improves our understanding of the quark-gluon structure of the nucleon. It provided th...
