具有高阶导数修正的EVH黑洞解

EVH Black Hole Solutions With Higher Derivative Corrections

Hossein Yavartanoo

摘要:

我们分析了四维极端消失视界(EVH)黑洞解的高阶导数修正对近视界几何的影响。我们限制自己的高斯-博内校正与膨胀依赖耦合在爱因斯坦麦克斯韦介子理论。这个作用量可以代表有效作用量,因为它出现在树水平的杂种弦论紧化到四维或K3紧化的II型弦论。我们表明,EVH黑洞,在这个理论中,开发一个AdS 3喉在其近地平线的几何形状。

英文摘要:

We analyze the effect of higher derivative corrections to the near horizon geometry of the extremal vanishing horizon (EVH) black hole solutions in four dimensions. We restrict ourselves to the Gauss-Bonnet correction with a dilation dependent coupling in an Einstein Maxwell dilaton theory. This action may represent the effective action as it arises in tree level heterotic string theory compactified to four dimensions or the K3 compactification of type II string theory. We show that EVH black holes, in this theory, develop an AdS3 throat in their near horizon geometry.
