Quadratic Curvature Corrections in Double Field Theory via Double Copy
Quadratic Curvature Corrections in Double Field Theory via Double Copy
Recent advances in the classical Double Copy (DC) procedure have revealed a profound connection between gauge theories and T-duality invariant frameworks, with Double Field Theory (the classical DC of Yang-Mills theory) emerging as the first explicit example. Extending this procedure to higher-derivative gauge theories predicts the existence of a Higher-Derivative …
