连续自旋的基本粒子

Elementary particles with continuous spin

Xavier Bekaert, Evgeny D. Skvortsov

摘要:

综述了具有“连续”自旋的基本粒子的经典理论结果和最新进展。在自由水平上,这些场由等距群(庞加莱群或反德西特群)的酉不可约表示描述,每个时空点具有无穷多个物理自由度。它们的基本群论和场论的描述进行了一些详细的审查。我们提出了一个未决问题清单,这些问题对于评估其实际状况和潜在相关性至关重要。

英文摘要:

Classical results and recent developments on the theoretical description of elementary particles with "continuous" spin are reviewed. At free level, these fields are described by unitary irreducible representations of the isometry group (either Poincaré or anti de Sitter group) with an infinite number of physical degrees of freedom per spacetime point. Their basic group-theoretical and field-theoretical descriptions are reviewed in some details. We mention a list of open issues which are crucial to address for assessing their physical status and potential relevance.
