新天堂双副本

New heavenly double copies

Erick Chacón, Hugo García-Compeán, Andres Luna, Ricardo Monteiro, Chris D. White

摘要:

双副本涉及散射振幅和经典的解决方案,杨米尔斯理论,重力,和相关的场论。先前的工作已经表明,这在自对偶YM理论中有明确的实现,其中运动方程可以写成一种形式,直接映射到普列巴斯基的自对偶引力天体方程。自对偶的YM方程涉及一个保面积的单态代数,在天球方程中出现了两个副本。在本文中,我们表明,这种结构是一个特殊的情况下,一个更广泛的家庭的天堂型的例子,(i)进行Moyal变形,(ii)更换面积保持同态与限制较少的代数。结果,我们得到了超埃尔米特流形的双拷贝解释,扩展了以前已知的超Kähler情况。我们还介绍了一个双Moyal变形的天球方程。拉克斯对的构造是可能的例子显然与沃德猜想一致,并表明引力型理论的经典可积性一般可以通过两个规范理论型单拷贝中至少一个的可积性来保证。

英文摘要:

The double copy relates scattering amplitudes and classical solutions in Yang-Mills theory, gravity, and related field theories. Previous work has shown that this has an explicit realisation in self-dual YM theory, where the equation of motion can be written in a form that maps directly to Plebański's heavenly equation for self-dual gravity. The self-dual YM equation involves an area-preserving diffeomorphism algebra, two copies of which appear in the heavenly equation. In this paper, we show that this construction is a special case of a wider family of heavenly-type examples, by (i) performing Moyal deformations, and (ii) replacing the area-preserving diffeomorphisms with a less restricted algebra. As a result, we obtain a double-copy interpretation for hyper-Hermitian manifolds, extending the previously known hyper-Kähler case. We also introduce a double-Moyal deformation of the heavenly equation. The examples where the construction of Lax pairs is possible are manifestly consistent with Ward's conjecture, and suggest that the classical integrability of the gravity-type theory may be guaranteed in general by the integrability of at least one of two gauge-theory-type single copies.
