混合对称的无约束高阶自旋。II。费米场

Unconstrained Higher Spins of Mixed Symmetry. II. Fermi Fields

Andrea Campoleoni, Dario Francia, Jihad Mourad, Augusto Sagnotti

摘要:

本文是arXiv:0810.4350 [hep-th]的续篇,也致力于研究平坦空间中混合对称的高自旋场的局部“类度规”无约束拉格朗日量和场方程。在这里,我们完成了以前的约束上壳制定的Labastida费米场,推导出相应的约束拉格朗日都通过Bianchi身份,并通过自伴的要求。我们还描述了两种类型的无约束拉格朗日公式:一个“最小”的,包含较高的衍生物的补偿字段,和另一个非最小的,只包含一个衍生条款。我们确定类这些系统下的Weyl对称变换是不变的。

英文摘要:

This paper is a sequel of arXiv:0810.4350 [hep-th], and is also devoted to the local "metric-like" unconstrained Lagrangians and field equations for higher-spin fields of mixed symmetry in flat space. Here we complete the previous constrained on-shell formulation of Labastida for Fermi fields, deriving the corresponding constrained Lagrangians both via the Bianchi identities and via the requirement of self-adjointness. We also describe two types of unconstrained Lagrangian formulations: a "minimal" one, containing higher derivatives of the compensator fields, and another non-minimal one, containing only one-derivative terms. We identify classes of these systems that are invariant under Weyl-like symmetry transformations.
