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…
Remarks on nonperturbative perturbations
Robert J. Saskowski
We consider the linearized perturbations of near-horizon extremal Reissner-Nordström black holes in -dimensional Einstein-Maxwell-Gauss-Bonnet gravity and seven-dimensional thir…
Multicenter higher-derivative BPS black holes
Yide Cai, Sabarenath Jayaprakash, James T. Liu +1
We consider the reduction of four-derivative heterotic supergravity on a torus and construct two-charge multicenter BPS black hole solutions. In , the three-form field can be…
