| dc.description | We analyze the singlet axial form factor of the proton for small momentum transferred in the framework of QCD sum rules using the interpolating nucleon current which explicitly accounts for the gluonic degrees of freedom. As a result we come to the quantitative description of the singlet axial constant: G_A(0)=0.2. The bilocal power corrections play the most important role in the analysis. | |

The higher twist bilocal power corrections are taken into account and continuum subtraction is reanalyzed. The corresponding change of singlet axial constant is within the experimental and theoretical errors | |
