连续自旋的BRST理论

BRST Theory for Continuous Spin

Anders K. H. Bengtsson

摘要:

讨论了闵可夫斯基时空中高自旋场论的一些令人困惑的问题,如无痕约束和寻找潜在的物理原理。最近研究得很多的庞加莱群的连续自旋表示可能提供了一个连接的想法。维格纳方程,作为第一类约束,产量的四个约束BRST制定。由此产生的场论,推广自由更高的自旋场论,是一组更高的自旋理论,可以涉及到以前的工作无约束配方之一。特别地,它被证实,Francia和Sagnotti的无约束高自旋理论是一个连续自旋理论的极限。此外,对约束结构的简单分析揭示了跟踪约束背后的物理原理的暗示。

英文摘要:

Some puzzling aspects of higher spin field theory in Minkowski space-time, such as the tracelessness constraints and the search for an underlying physical principle, are discussed. A connecting idea might be provided by the recently much researched continuous spin representations of the Poincaré group. The Wigner equations, treated as first class constraints, yields to a four-constraint BRST formulation. The resulting field theory, generalizing free higher spin field theory, is one among a set of higher spin theories that can be related to previous work on unconstrained formulations. In particular, it is conjectured that the unconstrained higher spin theory of Francia and Sagnotti is a limit of a continuous spin theory. Furthermore, a simple analysis of the constraint structure reveals a hint of a physical rationale behind the trace constraints.
