论文摘要
豪华实验（激光XFEL实验）是使用欧洲XFEL的电子束在Desy Hamburg计划的新实验。 Luxe旨在研究XFEL电子束的高强度光学激光器与16.5 GEV电子之间的碰撞，以及光激光器和高能二次光子之间的碰撞。 Luxe的物理目标是在强场边界处的量子电动力学（QED）过程，在该过程中，激光的电磁场高于Schwinger极限。在此制度中，QED是非扰动的。这体现在QED真空中的物理电子旋律对中，类似于黑洞的鹰辐射。 Luxe打算在前所未有的激光强度状态下衡量正电子产量。将对豪华实验设置及其挑战进行概述，然后在非扰动制度中测试QED的背景下讨论预期物理覆盖范围。
The LUXE experiment (LASER Und XFEL Experiment) is a new experiment in planning at DESY Hamburg using the electron beam of the European XFEL. LUXE is intended to study collisions between a high-intensity optical laser and 16.5 GeV electrons from the XFEL electron beam, as well as collisions between the optical LASER and high-energy secondary photons. The physics objective of LUXE are processes of Quantum Electrodynamics (QED) at the strong-field frontier, where the electromagnetic field of the laser is above the Schwinger limit. In this regime, QED is non-perturbative. This manifests itself in the creation of physical electron-positron pairs from the QED vacuum, similar to Hawking radiation from black holes. LUXE intends to measure the positron production rate in an unprecedented LASER intensity regime. An overview of the LUXE experimental setup and its challenges will be given, followed by a discussion of the expected physics reach in the context of testing QED in the non-perturbative regime.
