论文摘要
研究了在四维平坦空间中传播的大量和无质量的任意整数自旋场。通过使用轻度尺寸的螺旋基础形式主义来治疗庞大和无质量的领域。研究了大规模和无质量场之间的立方交叉交流，并研究了大规模田地之间的立方相互作用。我们介绍了此类立方相互作用的分类并使用我们的分类构建所有立方相互作用顶点。在相互作用场的空间上，发现了庞加雷代数的发生器。作为一种副产品，还讨论了三点不变的巨大和无质量领域的示例。
Massive and massless arbitrary integer spin fields propagating in four-dimensional flat space are studied. The massive and massless fields are treated by using a light-cone gauge helicity basis formalism. Cubic cross-interactions between massive and massless fields and cubic interactions between massive fields are investigated. We introduce a classification of such cubic interactions and using our classification we build all cubic interaction vertices. Realization of generators of the Poincare algebra on space of interacting fields is found. As a by-product, some illustrative examples of light-cone form for 3-point invariant amplitudes of massive and massless fields are also discussed.
