Minkowski空间中相对论性点粒子的路径积分

Path integral of the relativistic point particle in Minkowski space

Benjamin Koch, Enrique Muñoz

摘要:

在这篇文章中,我们分析了自由相对论性点粒子的作用所涉及的基本的整体和局部对称性。此外,我们确定了一个隐藏的局部对称性,其明确的考虑和因式分解利用Fujikawa处方,导致满足Chapman-Kolmogorov恒等式的相对论传播子的建设。通过一个详细的拓扑分析,我们找到了三个不同的相对论传播子(正交,类空,费曼),这是从在闵可夫斯基空间中的不同部门的道路的排他性整合。最后,这种方法的费曼棋盘结构的连接进行了探讨。

英文摘要:

In this article, we analyze the fundamental global and local symmetries involved in the action for the free relativistic point particle. Moreover, we identify a hidden local symmetry, whose explicit consideration and factorization utilizing of a Fujikawa prescription, leads to the construction of relativistic propagators that satisfy the Chapman-Kolmogorov identity. By means of a detailed topological analysis, we find three different relativistic propagators (orthochronous, space-like, and Feynman) which are obtained from the exclusive integration of paths within different sectors in Minkowski space. Finally, the connection of this approach to the Feynman checkerboard construction is explored.
