BRST Lagrangian construction for spin-2 field in Einstein space

I. L. Buchbinder, V. A. Krykhtin, P. M. Lavrov

摘要:

我们在高自旋场论中探索了一种新的BRST构造的可能性,以获得爱因斯坦空间中质量自旋为2的场的一致拉格朗日量。这种方法自动导致规范不变拉格朗日与适当的辅助和Stuckelberg领域。证明了在这种情况下,自旋为2的场的传播是双曲的和因果的。同时,我们也推广了自旋为2的场的部分无质量的概念。

英文摘要:

We explore a new possibility of BRST construction in higher spin field theory to obtain a consistent Lagrangian for massive spin-2 field in Einstein space. Such approach automatically leads to gauge invariant Lagrangian with suitable auxiliary and Stuckelberg fields. It is proved that in this case a propagation of spin-2 field is hyperbolic and causal. Also we extend notion of partial masslessness for spin-2 field in the background under consideration.
