球对称AdS_4中的静态超对称黑洞

Static supersymmetric black holes in AdS_4 with spherical symmetry

Kiril Hristov, Stefan Vandoren

摘要:

我们进一步阐述了在arXiv:0911.4926中发现的静态超对称AdS_4黑洞,在Fayet-Iliopoulos项的存在下,深入研究了N = 2规范超引力中球对称的BPS约束.我们发现杀死旋,保留两个原来的八个超荷和调查的条件,真正的黑洞裸奇点。视界的存在与标量不是常数的要求密切相关,而是以调和函数的形式给出,类似于无规范超引力中的吸引子流。黑洞的电荷取决于电磁测量的选择,只有磁荷用于纯电测量。最后,我们展示了这些黑洞是如何嵌入到N = 8的超引力中,从而嵌入到M理论中的。

英文摘要:

We elaborate further on the static supersymmetric AdS_4 black holes found in arXiv:0911.4926, investigating thoroughly the BPS constraints for spherical symmetry in N = 2 gauged supergravity in the presence of Fayet-Iliopoulos terms. We find Killing spinors that preserve two of the original eight supercharges and investigate the conditions for genuine black holes free of naked singularities. The existence of a horizon is intimately related with the requirement that the scalars are not constant, but given in terms of harmonic functions in analogy to the attractor flow in ungauged supergravity. The black hole charges depend on the choice of the electromagnetic gauging, with only magnetic charges for purely electric gaugings. Finally we show how these black holes can be embedded in N = 8 supergravity and thus in M-theory.
