论文摘要
使用标量QED可用于粒子碰撞的高能量实验，使用标量QED显示出三个带电的乳头之间的库仑散射是可扰动的。对于三胞胎相对动量，$ q_3 \ gtrsim 50 $ meV/$ c $，计算出的三杆子相关函数在$ o（α^2）$中与一对因子的常用三重产物非常相似 - 河滨近似。在较低的$ q_3 $中，但需要以$ \ sim15 $ mev/$ c $的最低实验测量，需要$ o（α^3）$或更高的条款，以获取令人信服的三杆库仑相互作用的说明。这与两杆子相关性相反，在该相关性相关性的情况下，在可比对相对矩A时，已知的精确溶液被较低的顺序显示为饱和。
The Coulomb scattering between three charged pions is shown to be perturbatively calculable using scalar QED for the relative momenta accessible to high-energy experiments of particle collisions. For the triplet relative momenta, $Q_3 \gtrsim 50$ MeV/$c$, the calculated three-pion correlation function at $O(α^2)$ is very similar to the commonly-used triple-product of pair factors -- Riverside approximation. At lower $Q_3$, but above the lowest existing experimental measurement of $\sim15$ MeV/$c$, terms of $O(α^3)$ or higher are needed to obtain a convincing description of three-pion Coulomb interactions. This is in contrast to two-pion correlations, for which the known exact solution is shown to be saturated by the lower orders at comparable pair relative momenta.
