D=5 BPS黑洞和黑洞环的近视界分析

Near-horizon analysis of D=5 BPS black holes and rings

Bernard de Wit, Stefanos Katmadas

摘要:

一个全面的分析,提出完全基于近地平线的数据,以确定吸引子方程和熵的BPS黑洞和环在5个时空维度,拉格朗日不变量下的8个超对称与高导数耦合。对于旋转的黑洞,结果只与以前工作的结果部分一致,在以前的工作中,经常使用额外的输入超出近视界行为。例如,关于小黑洞和大的自旋黑洞,仍然存在一些差异,这与高导数耦合的存在有关。本文提出了一些论点来解释其中的一些。对于黑环,由于陈-西蒙斯项的存在和规范场没有全局定义,分析是复杂的。来自高阶导数耦合的贡献采取系统的形式,与基于各种参数的期望一致。

英文摘要:

A comprehensive analysis is presented based exclusively on near-horizon data to determine the attractor equations and the entropy of BPS black holes and rings in five space-time dimensions, for a Lagrangian invariant under eight supersymmetries with higher-derivative couplings. For spinning black holes the results only partially agree with the results of previous work, where often additional input was used beyond the near-horizon behaviour. A number of discrepancies remains, for example, pertaining to small black holes and to large spinning black holes, which are related to the presence of the higher-derivative couplings. Arguments are presented to explain some of them. For the black rings, the analysis is intricate due to the presence of Chern-Simons terms and due to the fact that the gauge fields are not globally defined. The contributions from the higher-derivative couplings take a systematic form in line with expectations based on a variety of arguments.
