标题： Challenging Spontaneous Quantum Collapse with XENONnT

摘要： 我们报告了在XENONnT暗物质探测器首次科学运行中，利用1-140 keV低能电子反冲数据，对动态量子塌缩所预测的X射线辐射的搜索结果。自发辐射是动态塌缩模型不可避免的效果，这些模型被提出作为解决量子力学中长期存在的测量问题的一种可能方案。该分析利用了一种模型，首次考虑了由于氙原子中电子和质子电荷相反而在X射线范围内产生的发射光谱中的抵消效应。对马尔可夫连续自发定位模型和迪奥西-彭罗斯模型的自由参数设定了新的世界领先限制，分别比先前的最佳约束提高了两个数量级和五倍。实验上首次排除了连续自发定位模型中原先提出的强度和相关长度的初始值。 显示英文摘要

摘要： We report on the search for X-ray radiation as predicted from dynamical quantum collapse with low-energy electronic recoil data in the energy range of 1-140 keV from the first science run of the XENONnT dark matter detector. Spontaneous radiation is an unavoidable effect of dynamical collapse models, which were introduced as a possible solution to the long-standing measurement problem in quantum mechanics. The analysis utilizes a model that for the first time accounts for cancellation effects in the emitted spectrum, which arise in the X-ray range due to the opposing electron-proton charges in xenon atoms. New world-leading limits on the free parameters of the Markovian continuous spontaneous localization and Di\'osi-Penrose models are set, improving previous best constraints by two orders of magnitude and a factor of five, respectively. The original values proposed for the strength and the correlation length of the continuous spontaneous localization model are excluded experimentally for the first time.
