Description

η' dominance of form factors of the topological QCD current leads to an expression for the portion of the spin of the light vector mesons that is due to quarks. Vector dominance of the radiative decays of the η' is used to estimate the couplings of this meson to the vector ones. This results in the conclusion that only around 30% of the spin of these particles is due to quarks. Possible interpretations of this result are presented
