论文摘要
在这项工作中，我们从第一原则中得出了无质量螺旋性粒子的相对论波方程。我们从受限制的庞加莱集团的统一投影不可约的表示开始。我们定义了较弱的定位概念，尤其是找到任何无质量螺旋性粒子的位置操作员。因此，具有这些粒子的位置表示，我们在此表示中获得了波方程。我们将结果与文献中的先前发现进行了比较。
In this work, we derive from first principles the relativistic wave equation of massless particles of arbitrary helicity. We start from unitary projective irreducible representations of the restricted Poincaré group. We define a weaker notion of localization and find, in particular, a position operator for any massless particle of arbitrary helicity. Therefore, having the position representation for these particles, we obtain the wave equations in this representation. We compare our results with previous findings in the literature.
