用展开法计算深度非弹性散射中低x下粲结构函数$F^{c}_{k}(k = 2, L)$的比值

The Ratio of the Charm Structure Functions $F^{c}_{k}(k = 2, L)$ at Low x in Deep Inelastic Scattering with Respect to the Expansion Method

G. R. Boroun, B. Rezaei

摘要:

研究了低x值胶子分布函数的展开方法,并计算了LO和NLO分析中的粲结构函数。我们的研究结果提供了一个紧凑的比率$R^{c} =F^{c}_{L}/F^{c}_{2}$,这是近似独立的x和细节的部分子分布函数在低x值的公式。这个比值可以很好地探测由DESY HERA的约化粲截面推导出的质子中的粲结构函数$F^{c}_{2}$。这些结果表明,所得到的粲结构函数与HERA实验数据和其它理论模型相符合。

英文摘要:

We study the expansion method for the gluon distribution function at low x values and calculate the charm structure functions in the LO and NLO analysis. Our results provide a compact formula for the ratio $R^{c} =F^{c}_{L}/F^{c}_{2}$, which is approximately independent of x and the details of the parton distribution function at low x values. This ratio could be a good probe of the charm structure function $F^{c}_{2}$ in the proton deduced from the reduced charm cross sections at DESY HERA. These results show that the charm structure functions obtained are in agreement with HERA experimental data and other theoretical models.
