Higher-Derivative Corrections via the Double Copy Procedure
Eric Lescano, Jesús A. RodrÃguez
Recent advances in the off-shell formulation of the Double Copy (DC) procedure have revealed a profound connection between gauge theories and T-duality invariant frameworks. The ma…

The generalized Bergshoeff-de Roo identification
Walter H. Baron, Eric Lescano, Diego Marques
There are two main approaches to duality covariant first order higher derivative corrections to the heterotic string, one extending the duality structure and the other deforming th…

From noncommutative Yang-Mills to noncommutative gravity through a classical double copy map
Larisa Jonke, Eric Lescano
We compute the first nontrivial noncommutative correction to the Einstein-Hilbert Lagrangian, which arises from the double copy of noncommutative Yang-Mills theory (ncYM). We start…
