摘要:

我们简要地总结了我们最近改进的结果,以CCFR合作的实验数据$xF_3$结构函数的$νN$深非弹性散射在次次领头阶。特别注意的是提取的$α_s(M_Z)$和红外renormalon模型的参数$1/Q^2$ -校正在不同的微扰理论阶数。这些结果可能对计划使用中微子工厂未来可能的数据进行类似研究有意义。

英文摘要:

We briefly summarize the outcomes of our recent improved fits to the experimental data of CCFR collaboration for $xF_3$ structure function of $νN$ deep-inelastic scattering at the next-to-next-to-leading order. Special attention is paid to the extraction of $α_s(M_Z)$ and the parameter of the infrared renormalon model for $1/Q^2$-correction at different orders of perturbation theory. The results can be of interest for planning similar studies using possible future data of Neutrino Factories.
