Bhabha散射的双圈QED修正

Two-loop QED corrections to Bhabha scattering

Thomas Becher, Kirill Melnikov

摘要:

在所有运动学不变量都大于粒子质量的极限下,我们得到了规范理论中无质量和有质量散射振幅之间的一个简单关系。我们利用这个关系导出了大角度Bhabha散射的双圈QED修正。

英文摘要:

We obtain a simple relation between massless and massive scattering amplitudes in gauge theories in the limit where all kinematic invariants are large compared to particle masses. We use this relation to derive the two-loop QED corrections to large-angle Bhabha scattering.
