摘要:

介绍了AdS和Minkowski空间中有质量和无质量半整数高自旋场规范不变拉格朗日描述的最新进展。该过程是基于BFV-BRST算子,编码的初始条件实现的约束条件在Fock空间和提取的高自旋字段从酉不可约表示的AdS(庞加莱)群。该构造适用于具有多行Young tableaux的高自旋张量场。

英文摘要:

A recent progress in a gauge-invariant Lagrangian description of massive and massless half-integer higher-spin fields in AdS and Minkowski spaces is presented. The procedure is based on a BFV-BRST operator, encoding the initial conditions realized by constraints in a Fock space and extracting the higher-spin fields from unitary irreducible representations of the AdS (Poincare) group. The construction is applicable to higher-spin tensor fields with a multi-row Young tableaux.
