论文摘要
豪华实验（激光XFEL实验）是使用欧洲XFEL（EU.XFEL）的电子束在Desy Hamburg进行计划的实验。 Luxe旨在研究来自EU.xfel电子束的高强度光激光脉冲与16.5 GEV电子之间的碰撞，以及激光脉冲和高能二级光子之间的碰撞。这将阐明在强场边界的量子电动力学（QED），其中电子休息框架中激光的电磁场高于Schwinger极限。在此制度中，QED在电荷场耦合中是非扰动的。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。预计它将从2025年开始运行。将对豪华的实验设置及其挑战和进步进行概述，以及在非扰动制度中测试QED的背景下对预期物理覆盖率的讨论。
The LUXE experiment (Laser Und XFEL Experiment) is an experiment in planning at DESY Hamburg using the electron beam of the European XFEL (Eu.XFEL). LUXE is intended to study collisions between a high-intensity optical laser pulse and 16.5 GeV electrons from the Eu.XFEL electron beam, as well as collisions between the laser pulse and high-energy secondary photons. This will elucidate Quantum Electrodynamics (QED) at the strong-field frontier, where the electromagnetic field of the laser in the electron rest frame is above the Schwinger limit. In this regime, QED is non-perturbative in the charge field coupling. 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. It is expected to start running in 2025. An overview of the LUXE experimental setup and its challenges and progress will be given, along with a discussion of the expected physics reach in the context of testing QED in the non-perturbative regime.
