NNLO QCD ANALYSIS OF CCFR DATA ON XF(3) STRUCTURE-FUNCTION AND GROSS-LLEWELLYN-SMITH SUM-RULE WITH HIGHER TWIST AND NUCLEAR CORRECTIONS

A detailed NNLO QCD analysis of new CCFR data on the xF(3) structure f unction including the target mass, higher twist and nuclear correction s tvas performed and parametrizations of the perturbative and power te rms of the structure function were constructed. The results of QCD ana lysis of the structure function were used to study the Q(2)-dependence of the Gross-Llewellyn-Smith sum rule. The alpha S/pi-expansion of S- GLS(Q(2)) was studied and parameters of the expansion were found to be s(1) = 2.74 +/- 0.01, s(2) = -2.22 +/- 0.23, s(3) = -7.86 +/- 1.74 wh ich are in good agreement with the perturbative QCD predictions for th e Gross-Llewellyn-Smith sum rule in the next-to-leading and next-to-ne xt-to-leading order.
