酉割与Berry相位

Unitarity-Cuts and Berry's Phase

Pierpaolo Mastrolia

摘要:

阐述的观察,两个粒子的散射振幅的么正性切割可以通过应用斯托克斯定理计算,我们与光学定理的Berry相位,显示如何任意的单圈费曼振幅的虚部可以解释为一个复杂的2-形式的通量。

英文摘要:

Elaborating on the observation that two-particle unitarity-cuts of scattering amplitudes can be computed by applying Stokes' Theorem, we relate the Optical Theorem to the Berry Phase, showing how the imaginary part of arbitrary one-loop Feynman amplitudes can be interpreted as the flux of a complex 2-form.
