ResumoIt is suggested that an experimental verification of the relation ${A}_{2}={A}_{0}$ (${A}_{i}$ are the coefficients of the angular distribution of lepton pairs arising from decays of ${Z}^{0}$ produced at hadronic collisions) would be strong evidence for the vector nature of the spin of the gluon. The above relation ${A}_{2}={A}_{0}$ is badly broken if the gluon coupling to quarks violates quark-helicity conservation.
