Non-supersymmetric Extremal RN-AdS Black Holes in N=2 Gauged Supergravity

Tetsuji Kimura

摘要:

研究了四维N=2阿贝尔规范超引力中的极值Reissner-Nordstrom-AdS黑洞.我们找到了一个新的吸引子方程,它不是在渐近平坦时空中的一个。本文研究了具有单个中性矢量多重态的T^3-模型,得到了D 0-D4和D2-D 6电荷组态下具有规则事件视界的非超对称Reissner-Nordstrom-AdS黑洞解.负的宇宙学常数即使在没有费耶特-伊利奥普洛斯参数的情况下也会出现。此外,我们还讨论了T^3-模型和STU-模型在一般组态下的非超对称黑洞解的形式描述。

英文摘要:

We investigate extremal Reissner-Nordstrom-AdS black holes in four-dimensional N=2 abelian gauged supergravity. We find a new attractor equation which is not reduced to the one in the asymptotically flat spacetime. Focusing on so-called the T^3-model with a single neutral vector multiplet, we obtain non-supersymmetric extremal Reissner-Nordstrom-AdS black hole solutions with regular event horizon in the D0-D4 and the D2-D6 charge configurations. The negative cosmological constant emerges even without the Fayet-Iliopoulos parameters. Furthermore, we also argue the formal description of the non-supersymmetric black hole solutions of the T^3-model and the STU-model in generic configurations.
