S. Alexeyev, N. Popov, M. Startseva, A. Barrau, J. Grain

摘要:

Gauss-Bonnet引力理论为研究超对称弦论中爱因斯坦作用量的曲率修正提供了一个最有前途的框架,同时避免了鬼现象,保持了二阶场方程。虽然高斯-邦内黑洞的Schwarzschild型解早已为人所知,但Kerr-Gauss-Bonnet度规却一直缺失。本文解析地导出了自旋黑洞的五维Gauss-Bonnet近似,并简述了有关的物理性质。

英文摘要:

Gauss-Bonnet gravity provides one of the most promising frameworks to study curvature corrections to the Einstein action in supersymmetric string theories, while avoiding ghosts and keeping second order field equations. Although Schwarzschild-type solutions for Gauss-Bonnet black holes have been known for long, the Kerr-Gauss-Bonnet metric is missing. In this paper, a five dimensional Gauss-Bonnet approximation is analytically derived for spinning black holes and the related thermodynamical properties are briefly outlined.
