| contents | It is shown that the widely used parton model expression for $ g_1$ in polarized proton-lepton scattering is incorrect as it ignores gluon-quark spin entanglement. Therefore, there is no spin crisis. A brief summary of results of the theoretical evaluation of non-octet axial vector current renormalization constants and anomaly -anomaly vacuum correlator is given. It suggests that anomaly plays an important role in the transformation of current quarks to constituent quarks and chiral symmetry breaking. |
