Sea contributions and nucleon structure.

چکیده
We suggest a general formalism to treat a baryon as a composite system of three quarks and a ‘sea’. In this formalism, the sea is a cluster which can consists of gluons and quark-antiquark pairs. The hadron wave function with a sea component is given. The magnetic moments, related sum rules and axial weak coupling constants are obtained. The data seems to favor a vector sea rather than a scalar sea. The quark spin distributions in the nucleon are also discussed. 12.39.Jh, 13.30.Ce, 13.40.Em, 14.20.-c Typeset using REVTEX 1

We analyze the non-perturbative structure of the strange sea of the nucleon within a meson cloud picture. In a low Q approach in which the nucleon is viewed as a three valon bound state, we evaluate the probability distribution of an in-nucleon Kaon-Hyperon pair in terms of splitting functions and recombination. The resulting kaon and hyperon probability densities are convoluted with suitable s...
متن کامل1 J un 2 00 7 Global Analysis of Nucleon Strange Form Factors at Low Q 2
The existence of a “sea” of quarks and antiquarks in the nucleon has been firmly established in deep-inelastic lepton scattering experiments as well as in the production of dilepton pairs (the Drell-Yan process). However, demonstrating the role of these q̄q pairs in the static electromagnetic properties of the nucleon has been a more elusive and difficult task. As the lightest quark that contrib...

متن کاملParity Violation with Electrons and Hadrons
A key question in understanding the structure of nucleons involves the role of sea quarks in their ground state electromagnetic properties such as charge and magnetism. Parity-violating electron scattering, when combined with determination of nucleon electromagnetic form factors from parity-conserving e-N scattering, provides another degree of freedom to separately determine the up, down and st...
متن کاملHermes Measurement of the Spin Structure of the Nucleon
The HERMES experiment at the DESY Laboratory in Hamburg, Germany is designed to probe the spin structure of the nucleon by using deep inelastic scattering (DIS) of longitudinally polarized positrons on longitudinally and transversely polarized targets. The HERMES spectrometer has the ability to not only identify the scattered DIS positrons but as well the hadrons in coincidence with the scatter...
