Sea Quark Asymmetries in the Nucleon
نویسنده
چکیده
A physical model for parton densities in hadrons, based on Gaussian momentum fluctuations of partons and hadronic baryon-meson fluctuations, is presented. The model has previously been shown to describe proton structure function data, and is now applied to sea quark asymmetries and shown to describe the ¯ d − ¯ u asymmetry of the proton. By considering fluctuations involving strange quarks, the model gives an asymmetry between the momentum distributions of s and ¯ s, which would reduce the significance of the NuTeV anomaly.

Flavor Decomposition of the Nucleon A
I review some recent developments in the study of quark flavor distributions in the nucleon, including (i) valence quark distributions and the quark–hadron duality prediction for the x → 1 d/u ratio (ii) sea quark asymmetries and electromagnetic form factors (iii) strange quarks in the nucleon.
متن کاملQCD Spin Physics: Partonic Spin Structure of the Nucleon
We discuss some recent developments concerning the nucleon’s helicity parton distribution functions: New preliminary data from jet production at RHIC suggest for the first time a non-vanishing polarization of gluons in the nucleon. SIDIS measurements at COMPASS provide better constraints on the strange and light sea quark helicity distributions. Single-longitudinal spin asymmetries in W -boson ...
متن کاملDrell–yan Asymmetries at Hera- N 1
Structure functions measured in deep inelastic lepton–nucleon scattering probe a particular combination of quark distributions in the nucleon. The mere knowledge of these structure functions is therefore insufficient for a distinction between valence and sea quarks and for a further decomposition of the light quark sea into different flavours. These are only possible if additional information f...
متن کاملThe Quark - Antiquark Asymmetry of the Nucleon Sea from Λ and Λ Fragmentation
We present a general analysis of the spin transfer for Λ and Λ production in deepinelastic scattering of polarized charged leptons on the nucleon, and find that the pattern of different behaviors of Λ and Λ production observed by the E665 Collaboration suggests the possibility of quark-antiquark asymmetries either in the quark to Λ fragmentation functions and/or in the quark and antiquark distr...
متن کاملPerturbative generation of a strange-quark asymmetry in the nucleon.
We point out that perturbative evolution in QCD at three loops generates a strange-antistrange asymmetry s(x) - s(x) in the nucleon's sea just from the fact that the nucleon has nonvanishing up and down quark valence densities. The recently computed three-loop splitting functions allow for an estimate of this effect. We find that a fairly sizable asymmetry may be generated. Results for analogou...
