1304.1589 (Masashi Wakamatsu)

More on the relation between the two physically inequivalent
decompositions of the nucleon spin
   [PDF]

Masashi Wakamatsu
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.
