标题： Next-to-next-to-leading order QCD analysis of combined data for $xF_3$ structure function and higher--twist contribution

摘要： 同时对多个合作组在深度非弹性散射中测量的$xF_3$结构函数进行QCD分析，已达到QCD的三环阶。 高扭曲贡献的x依赖性得到评估，并与“旧”的CCFR数据分析结果以及重整子方法的预测定性一致。 Gross-Llewellyn Smith求和规则及其高扭曲修正得到评估。 显示英文摘要

摘要： The simultaneous QCD analysis of the $xF_3$ structure functions measured in deep-inelastic scattering by several collaborations is done up to 3--loop order of QCD. The x dependence of the higher--twist contribution is evaluated and turns out to be in a qualitative agreement with the results of "old" CCFR data analysis and with renormalon approach predictions. The Gross--Llewellyn Smith sum rule and its higher--twist corrections are evaluated.
