Title:More on the relation between the two physically inequivalent decompositions of the nucleon spin

Authors:Masashi Wakamatsu

Abstract:The recent controversy on the nucleon spin decomposition problem is critically overviewed. We argue that there exist two and only two physically inequivalent gauge-invariant decompositions of the longitudinal nucleon spin, contrary to the rapidly spreading view in the QCD spin physics community that there are infinitely many decompositions of the nucleon spin.
