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…
Non-Relativistic Limits of Bosonic and Heterotic Double Field Theory
Eric Lescano, David Osten
The known stringy non-relativistic (NR) limit of the universal NS-NS sector of supergravity has a finite Lagrangian due to non-trivial cancellations of divergent parts coming from…
Constructing Conformal Double Field Theory through a Double Copy Map
Eric Lescano, Jesús A. RodrÃguez
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 relat…
