双对数贡献引起的小x下DIS结构函数F_L的上升

Rise of the DIS structure function F_L at small x caused by double-logarithmic contributions

B. I. Ermolaev, S. I. Troyan

摘要:

本文给出了在双对数近似下F_L的计算,并证明了α_s^2阶因子1/x的协同作用和高阶全对数贡献的陡峭的x依赖性确保了F_L在小x和任意Q^2下的幂律上升。

英文摘要:

We present calculation of F_L in the double-logarithmic approximation and demonstrate that the synergic effect of the factor 1/x from the α_s^2-order and the steep x-dependence of the totally resummed double logarithmic contributions of higher orders ensures the power-like rise of F_L at small x and arbitrary Q^2.
