我们考虑五维Einstein-Gauss-Bonnet引力中的黑弦型解。数值构造的解决方案下静态，轴对称和几何不变的度量anonymous。的解决方案是指定的两个渐近费用：质量的黑弦和标量收费与半径的度量的一部分。当且仅当两个电荷满足微调关系时，才能找到正规黑弦解，否则时空会发展出奇异事件视界或裸奇异性。我们也可以通过使用双Wick旋转从黑弦生成泡解。
We consider black-string-type solutions in five-dimensional Einstein-Gauss-Bonnet gravity. Numerically constructed solutions under static, axially symmetric and translationally invariant metric ansatz are presented. The solutions are specified by two asymptotic charges: mass of a black string and a scalar charge associated with the radion part of the metric. Regular black string solutions are found if and only if the two charges satisfy a fine-tuned relation, and otherwise the spacetime develops a singular event horizon or a naked singularity. We can also generate bubble solutions from the black strings by using a double Wick rotation.
