Axial anomaly and the nucleon spin

Abstract

In this letter we have taken a particular Lagrangian, which was introduced to resolve U(1) problem, as an effective QCD Lagrangian, and have derived a formula of the quark content of the nucleon spin. The difference between quark content of the proton (ΔΣp) and that of the neutron (ΔΣn) is evaluated by this formula. Neglecting the higher-order iaospin corrections, this formula can reduce to Efremov's results in the large-Nc limit.
