高自旋混合对称场的类度规拉格朗日公式

Metric-like Lagrangian Formulations for Higher-Spin Fields of Mixed Symmetry

Andrea Campoleoni

摘要:

本文综述了平坦空间中混合对称的自由玻色子和费米子规范场的定域拉格朗日量和场方程的结构。这些首先提出了一个约束设置扩展的线性化重力的度量公式,然后($γ$ -)跟踪场和规范参数的限制,通过引入辅助字段被消除。我们还展示了在低时空维度的特定类别的模型中的Weyl对称性的出现。

英文摘要:

We review the structure of local Lagrangians and field equations for free bosonic and fermionic gauge fields of mixed symmetry in flat space. These are first presented in a constrained setting extending the metric formulation of linearized gravity, and then the ($γ$-)trace constraints on fields and gauge parameters are eliminated via the introduction of auxiliary fields. We also display the emergence of Weyl-like symmetries in particular classes of models in low space-time dimensions.
