异常过程与主导过程

Anomalous processes and leading logarithms

Karol Kampf

摘要:

综述了低能QCD奇本征扇区的研究现状。本文简要地讨论了中性π介子的双光子衰变,并分析了它与π介子衰变常数的关系。文中还介绍了一种理论工具--超前对数计算,指出了超前对数计算与异常扇区的关系,并给出了一些新的结果。

英文摘要:

Present status of odd-intrinsic sector of low energy QCD is summarized. The two-photon decay of neutral pion is shortly discussed and its connection with the pion decay constant is analysed. A theoretical tool, the leading-log calculation is also presented, its connection with anomalous sector shown and some new results given.
