强ChPT状态

Status of Strong ChPT

Johan Bijnens

摘要:

讨论了强介子区手征微扰理论的研究现状。对ChPT进行了非常简短的介绍,然后概述了现有的双回路计算和低能常数(LEC)的测定。我讨论的情况下,$η\toπππ$衰变在一定程度上更详细,并完成提到一些最近的工作部分淬火ChPT和重整化群在ChPT。

英文摘要:

The present status of Chiral Perturbation Theory (ChPT) in the strong mesonic sector is discussed. A very short introduction to ChPT is followed by an overview of existing two-loop calculations and the determination of the Low-Energy-Constants (LECs). I discuss the case of $η\toπππ$ decays in somewhat more detail and finish by mentioning some recent work on partially quenched ChPT and on the renormalization group in ChPT.
