摘要:

我们考虑的D-维共形不变积分,其中涉及自旋一半和自旋1粒子的评价。导出了无质量Yukawa理论的星三角关系,并确定了无质量QED三点格林函数的纵分量在位置空间的最低阶。计算无质量费曼积分的算子代数方法用于评估。

英文摘要:

We consider the evaluation of D-dimensional conformal invariant integrals which involve spin one-half and spin-one particles. The star-triangle relation for the massless Yukawa theory is derived, and the longitudinal part of the three-point Green function of massless QED is determined to the lowest order in position space. The operator algebraic method of calculating massless Feynman integrals is used for the evaluation.
