由基于Laplace变换的$F_{2}$参数化确定纵向结构函数$F_{L}$

A determination of the longitudinal structure function $F_{L}$ from the parametrization of $F_{2}$ based on the Laplace transformation

G. R. Boroun

摘要:

我计算纵向结构函数,使用拉普拉斯变换技术,从结构函数$F_{2}(x,Q^{2})$的参数化和它的衍生物在低值的Bjorken变量$x$。考虑了粲夸克质量对纵结构函数的影响,从而导致了$n_{f}=4$的标度变量。将结果与H1合作数据和CTEQ-Jefferson Lab(CJ)合作[Phys.Rev.D { \bf 93},114017(2016)]参数化模型进行比较。发现使用$x$的Bjorken变量获得的结果与L. P. Kaptari等人[Phys.Rev.D { \bf 99},096019(2019)]基于梅林变换技术的结果相当。

英文摘要:

I calculate the longitudinal structure function, using Laplace transform techniques, from the parametrization of the structure function $F_{2}(x,Q^{2})$ and its derivative at low values of the Bjorken variable $x$. I consider the effect of the charm quark mass to the longitudinal structure function, which leads to rescaling variable for $n_{f}=4$. The results are compared with the H1 collaboration data and the CTEQ-Jefferson Lab (CJ) collaboration [Phys.Rev.D {\bf93}, 114017 (2016)] parametrization model. The obtained results with the Bjorken variable of $x$ are found to be comparable with the results L.P.Kaptari et al. [Phys.Rev.D {\bf99}, 096019 (2019)] which is based on the Mellin transform techniques.
