SU中的$K\toππ$衰变(2)手征微扰理论

$K\toππ$ Decays in SU(2) Chiral Perturbation Theory

Johan Bijnens, Alejandro Celis

摘要:

我们在单圈双味手征微扰理论中研究了$K\toππ$衰变。我们提供的参数,为什么计算的系数的π手征对数$\logm = M^2\log M^2$是唯一的,然后进行计算。作为检查,我们执行已知的三味结果的减少。基本的论点预计是有效的较重的粒子和其他过程。

英文摘要:

We study the decays $K\toππ$ in one-loop two-flavour Chiral Perturbation Theory. We provide arguments why the calculation of the coefficient of the pionic chiral logarithm $\logm = M^2\log M^2$ is unique and then perform the calculation. As a check we perform the reduction of the known three-flavour result. The underlying arguments are expected to be valid for heavier particles and other processes as well.
