论文摘要
经典的双副本将确切的解决方案与BIADJOINT标量，仪表和重力理论相关联。最近，在Biad偶界理论中发现了非扰动溶液，该理论被推测与量规理论中的Wu-Yang单子相关。我们表明，通过考虑无限增强（冲击波）极限中的单极解决方案，似乎并非如此。此外，我们证明了Wu-Yang单子与Taub-nut溶液相关，其先前指出的单副本是Abelian样（Dirac）单极的副本。我们的结果表明，阿贝尔和非亚伯仪理论对象如何与同一重力对象相关联，并阐明许多有关经典双复制范围的开放问题。
The classical double copy relates exact solutions in biadjoint scalar, gauge and gravity theories. Recently, nonperturbative solutions have been found in biadjoint theory, which have been speculated to be related to the Wu-Yang monopole in gauge theory. We show that this seems not to be the case, by considering monopole solutions in the infinitely boosted (shockwave) limit. Furthermore, we show that the Wu-Yang monopole is instead related to the Taub-NUT solution, whose previously noted single copy is that of an abelian-like (Dirac) monopole. Our results demonstrate how abelian and non-abelian gauge theory objects can be associated with the same gravity object, and clarify a number of open questions concerning the scope of the classical double copy.
