论文摘要
在这项工作中，我通过第一个原理计算表明，量子状态描述了大量相对论的自由旋转颗粒遵守运动条件，这些条件可以将其起源可追溯到奇偶校验作为良好的量子数。这些条件是运动方程和相应场所满足的约束的根源。在无质量的限制中，定义明确的奇偶校验丢失了，但与非物理平价成分的任意变化有关。结果表明，这种新兴的对称性是著名的量规对称性。
In this work I show by a first principles calculation that quantum states describing massive relativistic free spinning particles obey kinematical conditions whose origin can be traced to parity as a good quantum number. These conditions are at the root of the equations of motion and of the constraints satisfied by the corresponding fields. In the massless limit, well defined parity is lost but a symmetry emerges related to arbitrary changes in the unphysical parity components. It is shown that this emergent symmetry is the celebrated gauge symmetry.
