(A)dS中的自旋2扭曲对偶

Spin-2 twisted duality in (A)dS

Nicolas Boulanger, Andrea Campoleoni, Ignacio Cortese, Lucas Traina

摘要:

本文从最近得到的Stueckelberg公式中自旋为2的(部分)无质量场的对偶拉格朗日量出发,将(A)dS中(部分)无质量引力子的运动方程写成扭曲对偶关系的形式.在这两种情况下,后者承认一个光滑平坦的极限。在无质量的情况下,这个极限再现了先前已知的闵可夫斯基时空的引力扭曲对偶关系。在部分无质量的情况下,我们的扭曲对偶关系在平坦极限下保持了自由度的数量,在这个意义上,它们分裂成自旋为1和自旋为2的场的一对解耦对偶。我们的结果适用于任何大于3维的时空。在四维空间中,部分无质量场的扭曲对偶关系,在文献中出现的恢复计量了施图克尔伯格场。

英文摘要:

Starting from the dual Lagrangians recently obtained for (partially) massless spin-2 fields in the Stueckelberg formulation, we write the equations of motion for (partially) massless gravitons in (A)dS in the form of twisted-duality relations. In both cases, the latter admit a smooth flat limit. In the massless case, this limit reproduces the gravitational twisted-duality relations previously known for Minkowski spacetime. In the partially-massless case, our twisted-duality relations preserve the number of degrees of freedom in the flat limit, in the sense that they split into a decoupled pair of dualities for spin-1 and spin-2 fields. Our results apply to spacetimes of any dimension greater than three. In four dimensions, the twisted-duality relations for partially massless fields that appeared in the literature are recovered by gauging away the Stueckelberg field.
