Generalized Bergshoeff-de Roo identification in the Supergravity frame
Walter H. Baron, Fabian A. Portilla
The paper refines the Generalized Bergshoeff‑de Roo identification to produce higher‑derivative couplings directly in the standard supergravity framework, using diffeomorphism, Lor…
The generalized Bergshoeff-de Roo identification II
Walter H. Baron, Diego Marques
We recently introduced a T-duality covariant mechanism to compute all-order higher-derivative interactions in the heterotic string. Here we extend the formalism to account for a tw…
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…
Tri-vector symmetry of 11 dimensional supergravity
Walter H. Baron, Diego Marques, Carmen A. Nunez +1
Kaluza-Klein reductions of 11-dimensional supergravity lead to exceptional global symmetries in lower dimensions. Certain non-geometric elements of these symmetries, parameterized…
symmetry in type II Supergravities
Walter H. Baron, Nahuel A. Yazbek
A non geometric sector of the duality group emerging in Kaluza-Klein reductions is realized as an effective symmetry in the low energy action of uncompactified type II theories. Th…
symmetry of heterotic supergravity
Walter H. Baron, Carmen A. Nunez, Jesus A. Rodriguez
The low energy effective action describing the Kaluza-Klein reduction of string theory on a -torus possesses a continuous O() global symmetry. The non-geometric piece of t…
