论文摘要
由于可以使用高阶扰动系列，因此必须使用OPE在QCD计算中包括非扰动效应。为了系统地确定非扰动效应并将其纳入理论计算，应解决肾上腺龙问题。我们使用使用傅里叶变换的肾上腺缩减方法来确定HQET的非扰动矩阵元素，$ \barλ$和$μ_π^2 $。这是$ u = 1 $ renormalon的第一个确定。
As higher order perturbative series are available, it is becoming necessary to include nonperturbative effects in QCD calculations using the OPE. In order to systematically determine nonperturbative effects and to incorporate them into theoretical calculations, the renormalon problem should be resolved. We use a renormalon subtraction method utilizing Fourier transform to determine nonperturbative matrix elements of HQET, $\barΛ$ and $μ_π^2$. This is the first determination performed with subtraction of the $u=1$ renormalon.
