低能极限下重夸克关联函数的高阶矩

Higher Moments of Heavy Quark Correlators in the Low Energy Limit at O(alpha_s^2)

A. Maier, P. Maierhoefer, P. Marquard

摘要:

本文给出了三圈重夸克关联函数的矢量、轴矢量、标量和赝标量的低能展开的前30阶矩,包括首次出现在三圈处的单重态贡献。此外,我们比较了大n的时刻的行为与阈值计算的预测。

英文摘要:

We present the first 30 moments of the low energy expansions of the vector, axial-vector, scalar and pseudo-scalar heavy quark correlation functions at three-loop order, including the singlet contribution which appears for the first time at three loops. In addition we compare the behavior of the moments for large n with the prediction from threshold calculations.
