关于自由高自旋场的高阶导数作用量的注记

A note on higher-derivative actions for free higher-spin fields

Euihun Joung, Karapet Mkrtchyan

摘要:

研究了自由高自旋场的高阶导数理论,重点是它们的对称性。推广熟悉的二阶导数约束的配方,我们首先构造较少约束的爱因斯坦和麦克斯韦等高导数的行动。然后,我们构造Weyl的行动-行动承认约束Weyl对称性-不同数量的衍生物。他们提出了一个因式分解的形式,利用爱因斯坦和麦克斯韦张量。类外尔作用量层级的最后一个(最高阶导数)成员与四维中的弗拉德金-蔡特林共形高自旋作用量相一致。

英文摘要:

Higher-derivative theories of free higher-spin fields are investigated focusing on their symmetries. Generalizing familiar two-derivative constrained formulations, we first construct less-constrained Einstein-like and Maxwell-like higher-derivative actions. Then, we construct Weyl-like actions - the actions admitting constrained Weyl symmetries - with different numbers of derivatives. They are presented in a factorized form making use of Einstein-like and Maxwell-like tensors. The last (highest-derivative) member of the hierarchy of the Weyl-like actions coincides with the Fradkin-Tseytlin conformal higher-spin action in four dimensions.
