Internal spin structure of the nucleon

摘要: The study of the structure proton and neutron through deep inelastic scattering, initially with electrons but subsequently muons neutrinos as well, has played a central role in establishing quark-parton theory composition hadrons quantum chromodynamics (QCD). One important aspect these theoretical experimental developments is two spin-dependent functions, which are independent spin-averaged functions define internal spin nucleon. Since both quarks gluons possess forces between them dependent, we can expect information on nucleon to be obtained spindependent aspects wave function, been case before atomic nuclear physics.
