Abstract

In this manuscript we confirm the presence of a Rindler horizon at CERN-NA63 by exploring its thermodynamics induced by the Unruh effect in their high energy channeling radiation experiments. By linking the entropy of the emitted radiation to the photon number, we find the measured spectrum to be a simple manifestation of the second law of Rindler horizon thermodynamics and thus a direct measurement of the recoil Fulling-Davies-Unruh (FDU) temperature. Moreover, since the experiment is born out of an ultra-relativistic positron, and the FDU temperature is defined in the proper frame, we find that temperature boosts as a length and thus fast objects appear colder. The spectrum also provides us with a simple setting to measure fundamental constants, and we employ it to measure the positron mass.

伦德勒视界的实验观察
在本文中,我们通过探索高能通道辐射实验中昂鲁效应引起的热力学,证实了CERN-NA63中伦德勒视界的存在。通过将发射辐射的熵与光子数联系起来,我们发现测量的光谱是伦德勒视界热力学第二定律的简单表现,因此可以直接测量后坐力富勒-戴维斯-安鲁(FDU)温度。此外,由于实验是在一个超相对论的正电子中产生的,并且FDU温度在适当的框架中被定义,我们发现温度随着长度的增加而增加,因此快的物体看起来更冷。光谱也为我们提供了一个测量基本常数的简单设置,我们用它来测量正电子的质量。
