论文摘要
经典的双副本与仪表，重力和其他理论的确切解决方案有关。尽管经过广泛的研究，但其适用性的起源和领域仍然神秘。在这封信中，我们表明，可以使用Twistor理论的良好想法来得出特定的化身 - Weyl Double拷贝。除了解释Weyl Double Copy的来源外，Twistor形式主义还表明，它比以前想象的要一般。
The classical double copy relates exact solutions of gauge, gravity and other theories. Although widely studied, its origins and domain of applicability have remained mysterious. In this letter, we show that a particular incarnation - the Weyl double copy - can be derived using well-established ideas from twistor theory. As well as explaining where the Weyl double copy comes from, the twistor formalism also shows that it is more general than previously thought.
