摘要:

我们提出了一个分析的$xF_3(x,Q^2)$结构函数和Gross-Llewellyn史密斯(GLS)求和规则考虑到核效应和更高的扭曲修正。该分析基于“N. M. Nath等人,Indian J Phys 90(1),117(2016)"。将几个早期分析中预测的核效应修正引入到自由核子的$xF_3(x,Q^2)$结构函数和GLS求和规则中,修正到次次领先阶(NNLO)微扰阶,计算了原子核的原子核结构函数和求和规则.此外,通过一个简单的模型,我们提取了高扭曲对非单重态结构函数$xF_3(x,Q^2)$和GLS求和规则在NNLO微扰级的贡献,并将其应用到我们的结果中.我们的NNLO结果以及核效应和更高的扭曲修正被观察到与相应的实验数据和其他唯象分析是兼容的。

英文摘要:

We present an analysis of the $xF_3(x,Q^2)$ structure function and Gross-Llewellyn Smith(GLS) sum rule taking into account the nuclear effects and higher twist correction. This analysis is based on the results presented in "N. M. Nath et al., Indian J Phys 90(1), 117 (2016)". The corrections due to nuclear effects predicted in several earlier analysis are incorporated to our results of $xF_3(x,Q^2)$ structure function and GLS sum rule for free nucleon, corrected upto next-next-to-leading order (NNLO) perturbative order and calculate the nuclear structure function as well as sum rule for nuclei. In addition, by means of a simple model we have extracted the higher twist contributions to the non-singlet structure function $xF_3(x,Q^2)$ and GLS sum rule in NNLO perturbative orders and then incorporated them to our results. Our NNLO results along with nuclear effect and higher twist corrections are observed to be compatible with corresponding experimental data and other phenomenological analysis.
