黑洞的结构提供了对引力理论的非线性方面的见解，并可以为广义相对论的修正提出可检验的预测。在这项工作中，我们研究确切的黑洞配置的矢量张量理论，最初提出解释暗能量通过打破阿贝尔对称性与非最小耦合的矢量重力。我们能够回避贝肯斯坦关于具有普罗卡质量项的矢量张量理论中规则黑洞存在性的不通过定理，并展示具有纵向矢量极化轮廓的规则黑洞解，其特征是附加电荷。我们分析找到最一般的静态，球对称黑洞的解决方案，并没有宇宙常数，并研究了一些详细的功能，如几何形状如何依赖于矢量电荷。我们还包括角动量，并找到描述缓慢旋转的黑洞的解决方案。最后，我们将其中一些解决方案扩展到更高的维度。
Black hole configurations offer insights on the nonlinear aspects of gravitational theories, and can suggest testable predictions for modifications of General Relativity. In this work, we examine exact black hole configurations in vector–tensor theories, originally proposed to explain dark energy by breaking the Abelian symmetry with a non-minimal coupling of the vector to gravity. We are able to evade the no-go theorems by Bekenstein on the existence of regular black holes in vector–tensor theories with Proca mass terms, and exhibit regular black hole solutions with a profile for the longitudinal vector polarisation, characterised by an additional charge. We analytically find the most general static, spherically symmetric black hole solutions with and without a cosmological constant, and study in some detail their features, such as how the geometry depends on the vector charges. We also include angular momentum, and find solutions describing slowly-rotating black holes. Finally, we extend some of these solutions to higher dimensions.
