Aspects of conformal gravity and double field theory from a double copy map
Double field theory (DFT) can be constructed as the double copy of a Yang-Mills theory. In this work we extend this statement by including higher-derivative terms. Starting from a four-derivative extension of Yang-Mills theory whose double copy is known to correspond to a conformal-gravity theory, we obtain a four-derivative theory …
