论文摘要
在本文中，我们考虑了d = 3中巨大的较高自旋玻色子和费米子的类似框架的规格不变描述，并首次提供了证明这种配方确实仅描述了一个巨大的物理自由度，并具有适当的螺旋性。为此，我们完全修复了所有规格对称性，并表明所有其他辅助组件都消失了壳，而唯一剩下的最高组件满足了正确的方程。作为奖励，我们表明，Aragone和Khoudeir提出的所谓的自二巨型Spin-3和Spin-4字段的Lagrangians（以及它们对任意整数和半整数旋转的概括）提出的，可通过适当的尺寸固定从规范的不变型中获得。
In this paper we consider a frame-like gauge invariant description of massive higher spin bosons and fermions in d=3 and provide for the first time a proof that such formulation does describe just one massive physical degree of freedom with the appropriate helicity. For this purpose we completely fix all the gauge symmetries and show that all other auxiliary components vanish on-shell, while the only remaining highest component satisfies the correct equations. As a bonus, we show that the Lagrangians for the so-called self-dual massive spin-3 and spin-4 fields proposed by Aragone and Khoudeir (as well as their generalization to arbitrary integer and half-integer spins) can be obtained from the gauge invariant ones by the appropriate gauge fixing.
