Scientific paper
We consider the issue of an accurate description of the evolution of the non-singlet structure function moments $M_n(Q)$ near heavy quark threshold. To this aim we propose a simple modification of the standard massless \MSbar scheme approach to the next-to-leading QCD analysis of DIS data. We apply it to the processing of the modern CCFR'97 data for $xF_3$ structure function and extract the value of $\alpha_s(M_z) \approx 0.122 \pm 0.004$ We check also the consistency of light gluino hypothesis with CCFR'97 data.
