Quantum Statistical Parton Distributions and the Spin Crisis : Nuclear Physics

概要

論文の詳細を見る
Quantum statistical distributions for partons provide a fair description of deep inelastic scattering data at Q^2=3 and 10(GeV/c)^2. Study of the polarized structure functions seems to suggest an alternative possible solution of the spin crisis based on the Pauli principle. In this scheme, in fact,it becomes apparent that the defects of the Gottfried sum rule and Ellis-Jaffe sum rule for the proton are strongly connected. This possibility finds particular evidence from the phenomenological observation that the relation ⊿u =2F^^〜 + u - d - 1 seems to be satisfied well by parton distributions.
