标题： Field signature for apparently superluminal particle motion

摘要： 在Stueckelberg协变辛力学的背景下，Horwitz和Aharonovich提出了一种简单的机制，通过该机制，一个几乎处处以低于光速运动的粒子可能表现出暗示超光速运动的渡越时间。这种机制需要精确测量粒子的速度，涉及由虚粒子对过程引起的对粒子记录的时间坐标的微妙扰动。Stueckelberg框架特别适合此类问题，因为它允许在经典层面上发生粒子对的产生/湮灭。在本文中，我们研究了Horwitz和Aharonovich提出的轨迹类型，并推导出与运动相关的麦克斯韦四维势。我们证明了由此产生的场携带与表观超光速运动相关的特征标记，为该机制提供了独立的验证，除了在探测器处外，不需要直接观测轨迹。 显示英文摘要

摘要： In the context of Stueckelberg's covariant symplectic mechanics, Horwitz and Aharonovich have proposed a simple mechanism by which a particle traveling below light speed almost everywhere may exhibit a transit time that suggests superluminal motion. This mechanism, which requires precise measurement of the particle velocity, involves a subtle perturbation affecting the particle's recorded time coordinate caused by virtual pair processes. The Stueckelberg framework is particularly well suited to such problems, because it permits pair creation/annihilation at the classical level. In this paper, we study a trajectory of the type proposed by Horwitz and Aharonovich, and derive the Maxwell 4-vector potential associated with the motion. We show that the resulting fields carry a signature associated with the apparent superluminal motion, providing an independent test for the mechanism that does not require direct observation of the trajectory, except at the detector.
