Flavor asymmetry of the nucleon sea: Consequences for dilepton production.
نویسندگان
چکیده
Parton distributions derived from a chiral quark model that generates an excess of down quarks and antiquarks in the proton's sea satisfactorily describe the measured yields of muon pairs produced in proton-nucleus collisions. Comparison of dilepton yields from hydrogen and deuterium targets promises greater sensitivity to the predicted flavor asymmetry.

Light flavor sea-quark asymmetry for the spin-dependent distribution functions of the nucleon
The theoretical predictions of the chiral quark soliton model for the unpolarized and longitudinally polarized structure functions of the nucleon are compared with recent high energy data. The theory is shown to explain all the qualitatively noticeable features of the existing experiments, including the light flavor sea-quark asymmetry for the unpolarized distribution functions established by t...
متن کاملPhenomenological constraints on the flavour asymmetry of the nucleon sea
We study the possible flavour asymmetry, ū 6= d̄, of the light quark sea distributions of the proton. We discuss the information that is at present available from data on deep-inelastic lepton-nucleon scattering and from DrellYan production on various nuclear targets. We show that the ratio of dilepton yields on hydrogen and deuterium targets is very sensitive to ū − d̄. The increased precision o...
متن کاملFlavor asymmetry of the nucleon sea
One of the most active areas of research in nuclear and particle physics during the last several decades is the study of quark and gluon distributions in the nucleons and nuclei. Several major surprises were discovered in Deep-Inelastic Scattering (DIS) experiments which profoundly changed our views of the partonic substructure of hadrons. In the early 1980’s, the famous ‘EMC’ effect found in m...
متن کاملFlavor Structure of the Nucleon Sea
The recent progress on our understanding of the flavor structure of unpolarized and polarized nucleon sea is reviewed. The large flavor asymmetry between the up and down sea quark distributions is now well established. This asymmetry strongly suggests the importance of the mesonic degrees of freedom in the description of the nucleon sea. The strong connection between the flavor structure and th...
متن کاملOff-shell pion structure function and flavor asymmetry in the nucleon sea
We study off-shell effects of the pion cloud on the sea quark distribution in the nucleon. The structure function of the off-mass-shell pion is obtained within the Nambu and Jona-Lasinio model, where the shape of the distribution function depends on the pion momentum. By using the momentum dependent pion structure function, the SU(2) flavor asymmetry in the nucleon see is reexamined within the ...
