Eric Lescano, Jesús A. Rodríguez

AI总结:

本文将经典 Double Copy 程序应用于四阶导数规范理论,构建了包含 Weyl 引力的共形双场论,揭示了规范理论与 T-duality 不变模型间的深刻联系。

摘要:

我们遵循联系 Yang-Mills 与 Double Field Theory (DFT) 的经典 Double Copy (DC) 程序,并将其应用于一个已知在振幅层面与 Weyl 引力相关的四阶导数规范理论。我们在双几何上获得了一个微扰 T-duality 不变理论,即 Conformal Double Field Theory (CDFT),在二次阶包含了 Weyl 引力以及 $b$-field 和 dilaton 的贡献,且无需施加规范固定条件。我们还将公式化扩展到了广义 dilaton 为零时的三次阶,当 $\Box h_{μν}=h=0$ 时,该理论依然包含 Weyl 引力。CDFT 与普通 DFT 一起,构成了通过经典 DC 映射构建的 T-duality 不变理论的实例,揭示了规范理论与 T-duality 不变模型之间充满前景的深刻联系。

英文摘要:

We follow the classical Double Copy (DC) procedure that links Yang-Mills and Double Field Theory (DFT), and we apply it on a four-derivative gauge theory which is known to be related to Weyl gravity at the level of the amplitudes. We obtain a perturbative T-duality invariant theory on a double geometry, or Conformal Double Field Theory (CDFT), incorporating Weyl gravity plus $b$-field and dilaton contributions at quadratic order, without the need to impose a gauge fixing condition. We also extend the formulation to cubic order for the case of vanishing generalized dilaton, which still incorporates Weyl gravity when $\Box h_{μν}=h=0$. CDFT, together with ordinary DFT, are examples of T-duality invariant theories constructed through classical DC maps, revealing a promising and deep connection between gauge theories and T-duality invariant models.
