Roles of Diquarks in the Nucleon for the Deep Inelastic Scattering and the Non-leptonic Weak Transitions
نویسنده
چکیده
We study roles of quark-quark correlations in the baryons for the deep inelastic structure function and the I = 1=2 rule of the non-leptonic weak hyperon decay. The quark-quark correlation is incorporated phenomenologically as diquarks within the Nambu and Jona-Lasinio model. The strong diquark correlations in the spin-0 channel enhance the I = 1=2 weak matrix elements, and account for the I = 1=2 rule. The ratio of the nucleon structure functions F n 2 (x)=F p 2 (x) also comes to agree with experiment due to the diquark correlations.

O(α) QED Corrections to Neutral Current Polarized Deep–Inelastic Lepton–Nucleon Scattering
The O(α) leptonic QED corrections to neutral current polarized deep inelastic lepton– nucleon scattering are calculated in leptonic variables both for the case of longitudinal and transverse nucleon polarization. The results of the complete calculation are compared with the corresponding leading log expressions. Numerical results are presented for the corrections in the kinematic range of the H...

Deep inelastic scattering provides us with detailed information on the nucleon structure. In order to extract the parton distribution functions from DIS cross sections and to measure αs(M 2 Z) with high precision it is crucial to control the QED radiative corrections. The 1– and 2–loop leading–log QED corrections were derived in Ref. [1–3]. Complete 1-loop corrections for DIS were given in Refs...

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...

In inclusive deep-inelastic lepton-hadron scattering multi-photon exchange between the leptonic and the hadronic part of the process causes single spin asymmetries. The asymmetries exist for a polarized target as well as a polarized incoming or outgoing lepton, if the polarization vector has a component transverse with respect to the reaction plane. The spin dependent parts of the single polari...
متن کاملSivers Asymmetries for Inclusive Pion and Kaon Production in Deep-Inelastic Scattering
We calculate the Sivers distribution functions induced by the final-state interaction due to one-gluon exchange in diquark models of nucleon structure, treating the cases of scalar and axial-vector diquarks with both dipole and Gaussian form factors. We use these distribution functions to calculate the Sivers single-spin asymmetries for inclusive pion and kaon production in deep-inelastic scatt...
