摘要

我们提出了一个新的精确黑洞解的五维weyl -几何高斯-邦纳引力理论。欧几里得扇形定义了一个与Weyl向量场耦合的完全正则度规。计算了欧几里得作用和熵，后者遵循简单的A/4形式加上一个在视界半径上的线性项，具有高斯-博内耦合的特征。

An exact five dimensional Weyl-geometry Gauss-Bonnet black hole

We present a new exact black hole solution of a 5-dimensional Weyl-geometry Gauss-Bonnet theory of gravity. The Euclidean sector defines a fully regular metric coupled to the Weyl vector field. The Euclidean action and entropy are computed, with the latter following the simple

form plus a term linear in the horizon radius, characteristic of Gauss-Bonnet couplings.
