论文摘要
在日常研究中，默默假设散射横截面具有给定粒子物种，质量中心能量和粒子极化的固定值。但是，在几次抑制高能量bremsstrahlung的观察结果之后，该假设已受到质疑。这个过程将在未来的电子离子对撞机的实验中起主要作用，我们在这里展示了如何使用侧向束位移对Bremsstrahung横截面的变化进行深入研究。特别是，我们预测观测到的大型横截面的大型横截面非常强大。我们还讨论了这些难以捉摸的效应与宏观距离发生的其他量子现象的关系。在这种情况下，还评估了EIC相干bremsstrahlung的壮观且可能有用的特性。
In everyday research, it is tacitly assumed that the scattering cross-sections have fixed values for the given particle species, centre-of-mass energy, and particle polarizations. However, this assumption has been called into question after several observations of suppression of high-energy bremsstrahlung. This process will play a major role in experiments at the future Electron-Ion Collider, and we show here how variations of the bremsstrahlung cross-section can be profoundly studied there using the lateral beam displacements. In particular, we predict very strong increase of the observed cross-sections for large beam separations. We also discuss the relation of these elusive effects to other quantum phenomena occurring over macroscopic distances. In this context, spectacular and possibly useful properties of the coherent bremsstrahlung at the EIC are also evaluated.
