几何质量更高自旋和电流交换

Geometric massive higher spins and current exchanges

Dario Francia

摘要:

广义菲尔茨-泡利质量项允许通过相应的几何无质量拉格朗日量的简单二次变形来描述平坦背景上的大质量高自旋场。在这个框架中,不需要辅助字段。我们简要回顾了玻色子情况下的建设和研究这些大规模的领域与外部源的相互作用,计算相应的传播子。与有质量引力子的情况相同,但与存在辅助场的理论不同,电流交换的结构完全由质量项本身的形式决定。

英文摘要:

Generalised Fierz-Pauli mass terms allow to describe massive higher-spin fields on flat background by means of simple quadratic deformations of the corresponding geometric, massless Lagrangians. In this framework there is no need for auxiliary fields. We briefly review the construction in the bosonic case and study the interaction of these massive fields with external sources, computing the corresponding propagators. In the same fashion as for the massive graviton, but differently from theories where auxiliary fields are present, the structure of the current exchange is completely determined by the form of the mass term itself.
