讨论了小x恢复在类时运动学中的地位。我们给出了在MS分解方案中提取x的大对数并将其还原为封闭形式的一般过程。本文将回顾双对数恢复系数函数的新结果。我们所有的恢复公式都与其他小组最近在ar{MS}方案中完成的固定NNLO计算一致。
The status of small x resummation in the timelike kinematics is discussed. We present a general procedure to extract the large logarithms of x in the MS factorization scheme and to resum them in a closed form. New results for the doubly-logarithm-resummed coefficient functions will be reviewed. All our resummation formulae are in agrement with the fixed NNLO computations recently done by other groups in the ar{MS} scheme.
