摘要

Results of LO Fixed point QCD (FP-QCD) analysis of the CCFR data for the nucleon structure function xF(sub 3) (x,Q(sup 2)) are presented. The predictions of FP-QCD, in which (alpha)(sub S) (Q(sup 2)) tends to a nonzero coupling constant (alpha)(sub 0) as Q(sup 2) (yields) (infinity), are in good agreement with the data. The description of the data is even better than that in the case of LO QCD. The FP-QCD parameter (alpha)(sub 0) is determined with a good accuracy: (alpha)(sub 0) 0.198 (+-) 0.009. Having in mind the recent QCD fits to the same data we conclude that unlike the high precision and large (x,Q(sup 2)) kinematic range of the CCFR data they cannot discriminate between QCD and FP-QCD predictions for xF(sub 3) (x,Q(sup 2)). 11 refs., 1 tab.
