Boundary terms and conserved charges in higher-derivative gauged supergravity
Davide Cassani, Alejandro Ruipérez, Enrico Turetta
We address some issues in higher-derivative gauged supergravity with Chern-Simons terms, focusing on the five-dimensional case. We discuss the variational problem with Dirichlet bo…
Open Strings in IIB Orientifold Reductions
Juan R. Balaguer, Giuseppe Dibitetto, Jose J. Fernandez-Melgarejo +1
We consider type IIB compactifications on a general 4D group manifold with different types of possible spacetime filling O-planes and the corresponding D-branes parallel to them. O…
Beyond the near-horizon limit: Stringy corrections to Heterotic Black Holes
Pablo A. Cano, Samuele Chimento, Patrick Meessen +3
We study the first-order in corrections to 4-charge black holes (with the Reissner-Nordström black hole as a particular example) beyond the near-horizon limit in the Heterotic…
Regular Stringy Black Holes?
Pablo A. Cano, Samuele Chimento, Tomas Ortin +1
We study the first-order corrections to the singular 4-dimensional massless stringy black holes studied in the nineties in the context of the Heterotic Superstring. We show th…
On a family of -corrected solutions of the Heterotic Superstring effective action
Samuele Chimento, Patrick Meessen, Tomas Ortin +2
We compute explicitly the first-order in corrections to a family of solutions of the Heterotic Superstring effective action that describes fundamental strings with momentum al…
Supersymmetric solutions of the cosmological, gauged, C magic model
Samuele Chimento, Tomas Ortin, Alejandro Ruiperez
We construct supersymmetric solutions of theories of gauged supergravity coupled to vector multiplets with a Abelian (Fayet-Iliopoulos)…
