Title: 真空的相对论不变性

Abstract: Relativistic invariance of the vacuum is (or follows from) one of the Wightman axioms which is commonly believed to be true. Without these axioms, here we present a direct and general proof of continuous relativistic invariance of all real-time vacuum correlations of fields, not only scattering (forward in time), based on closed time path formalism. The only assumptions are basic principles of relativistic quantum field theories: the relativistic invariance of the Lagrangian, of the form including known interactions (electromagnetic, weak and strong), and standard rules of quantization. The proof is in principle perturbative leaving a possibility of spontaneous violation of invariance. Time symmetry is however manifestly violated. Show Chinese abstract

Abstract: 真空的相对论不变性是一组通常被认为正确的维格纳公理之一。如果没有这些公理，我们在这里直接且一般地证明了场的所有实时间真空关联的连续相对论不变性，不仅包括散射（向前时间），这是基于闭合时间路径形式体系。唯一的假设是相对论量子场理论的基本原理：拉格朗日的相对论不变性，包括已知相互作用（电磁、弱和强）的形式，以及标准的量子化规则。该证明原则上是微扰性的，留下了自发违反不变性的可能性。然而，时间对称性被明显违反。
