论文摘要
Desy Hamburg提出的豪华实验（激光XFEL实验）使用来自欧洲XFEL的电子束，目的是在高强度激光脉冲和高能量脉冲和高能量电子束之间碰撞中探测QED。该设置还提供了一个独特的机会，可以探究标准模型以外的物理。在此程序中，我们表明，通过利用Luxe产生的大光子通量，可以探测类似轴的样粒子（ALP），质量为350 MeV，并且具有$ 3 \ times {10}^{ - 6}^{ - 6}^{-6} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ {此范围与Na62的无背景投影相当。此外，我们将讨论其他新物理学（例如ALP-Electron耦合）的探针。
The proposed LUXE experiment (Laser und XFEL Experiment) at DESY Hamburg, using the electron beam from the European XFEL, aims to probe QED in the non-perturbative regime created in collisions between high-intensity laser pulses and high-energy electron or photon beams. This setup also provides a unique opportunity to probe physics beyond the standard model. In this proceedings, we show that by leveraging the large photon flux generated at LUXE, one can probe axion-like-particles (ALPs) up to a mass of 350 MeV and with a photon coupling of $3\times{10}^{-6}\ \mathrm{GeV}^{-1}$. This reach is comparable to the background-free projection from NA62. In addition, we will discuss other probes of new physics such as ALPs-electron coupling.
