分数阶解析微扰理论中的双环恢复

Two-loop Resummation in Fractional Analytic Perturbation Theory

Alexander P. Bakulev

摘要:

这个演讲描述了量子色动力学中的(分数)解析微扰理论(FAPT)中的重算方法。首先,我们对(F)APT方法进行了简短的历史回顾,然后简要描述了FAPT的全球计划,该计划允许考虑重夸克阈值。之后,我们展示了如何在(F)APT中在单循环和双循环近似中恢复非幂级数。作为一个应用程序,我们建议我们的希格斯玻色子衰变${H^0\to b\bar{b}}$,重要的大型强子对撞机计划,和矢量电流阿德勒功能的分析。

英文摘要:

This talk describes the resummation approach in (Fractional) Analytic Perturbation Theory (FAPT) in QCD. First, we make a short historical review of the (F)APT approach and then shortly describe the global scheme of FAPT which allows one to take into account heavy-quark thresholds. After that we show how it is possible to resum a non-power series in (F)APT both in the one- and two-loop approximations. As an application we suggest our analysis of the Higgs boson decay ${H^0\to b\bar{b}}$, important for the LHC program, and of the vector-current Adler function.
