BMPV black holes in higher-derivative supergravity
Yide Cai, Sabarenath Jayaprakash, James T. Liu +2
There are five independent four-derivative superinvariants for the five-dimensional STU model, of which two are vector invariants that do not involve curvature tensors. We construc…
What U Can Do: New Solutions and New Challenges Beyond Leading Order
Yi Pang, Robert J. Saskowski
String theories naturally exhibit dualities that lead to hidden symmetries in the low-energy effective description, which have been used to great effect to generate supergravity so…
Symmetries of non-maximal supergravities with higher-derivative corrections
Yi Pang, Robert J. Saskowski
We consider hidden symmetries arising from U-duality in the dimensional reduction of non-maximal higher-derivative supergravities to three dimensions. In particular, we consider th…
New invariants in five-dimensional supergravity
Yide Cai, Sabarenath Jayaprakash, James T. Liu +2
We consider four-derivative superinvariants of five-dimensional supergravity coupled to vector multiplets, which we obtain from both the superconformal te…
Consistent Four-derivative Heterotic Truncations and the Kerr-Sen Solution
Liang Ma, Yi Pang, Robert J. Saskowski +1
Four-derivative heterotic supergravity (without gauge fields) reduced on a -dimensional torus leads to half-maximal supergravity coupled to vector multiplets, and it is know…
Higher-derivative Heterotic Kerr-Sen Black Holes
Peng-Ju Hu, Liang Ma, Yi Pang +1
We obtain the four-derivative corrections to the Kerr-Sen solution in heterotic supergravity, which includes the Gibbons-Maeda-Garfinkle-Horowitz-Strominger solution as a limiting…
