چکیده
|
We analyze bps black hole attractors in 4d gauged supergravity in the presence of higher derivative supersymmetric terms, including a weyl-squared-type action, and determine the resulting corrections to the bekenstein-hawking entropy. the near-horizon geometry ads2×s2 (or other riemann surface) preserves half of the supercharges in n = 2 supergravity with fayet-iliopoulos gauging. we derive a relation between the entropy and the black hole charges that suggests via ads/cft how subleading corrections contribute to the supersymmetric index in the dual microscopic picture. depending on the model, the attractors are part of full black hole solutions with different asymptotics, such as minkowski, ads4, and hvlif4. we give explicit examples for each of the asymptotic cases and comment on the implications. among other results, we find that the weyl-squared terms spoil the exact two-derivative relation to non-bps asymptotically flat black holes in ungauged supergravity.
