Constructing conformal double field theory through a double copy map

Year: 2025

Type: article

Abstract: We follow the classical double copy (DC) procedure that links Yang-Mills and double field theory (DFT), and 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 □ h μ ν = 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.
