论文摘要
在这份简短的报告中,我们调查了爱因斯坦 - 复杂的 - 复合体 - 刻板 - 斯卡尔 - 高斯 - 高斯 - 高斯 - 高斯(ECSGB)重力的4维静态对称黑洞(BHS)的存在,具有任意潜在$ v(ϕ)$和cOUPLAINT $ f(ϕ)$ f(ϕ)$ f(GB)$ cuss $ F(GB)(GB)$ f(ϕ)$ f(ϕ)$(GB)(GB)(GB)(GB)(gb)(GB)(GB)(GB)(GB)(GB)(GB)(GB)(GB)(GB)。我们发现不存在具有复杂标质头发的静态常规BH溶液。该结论不取决于GB项和标量场之间的耦合,也不取决于标量电势V(ϕ)$以及存在宇宙常数$λ$(可以是正或负)的存在,因为标量场保持复杂,并且在整个地平线上是正常的。
In this brief report, we investigate the existence of 4-dimensional static spherically symmetric black holes (BHs) in the Einstein-complex-scalar-Gauss-Bonnet (EcsGB) gravity with an arbitrary potential $V(ϕ)$ and a coupling $f(ϕ)$ between the scalar field $ϕ$ and the Gauss-Bonnet (GB) term. We find that static regular BH solutions with complex scalar hairs do not exist. This conclusion does not depend on the coupling between the GB term and the scalar field, nor on the scalar potential $V(ϕ)$ and the presence of a cosmological constant $Λ$ (which can be either positive or negative), as longer as the scalar field remains complex and is regular across the horizon.
