In this paper, we analytically present an exact confining charged black hole solution to the scalar-tensor description of regularized 4-dimensional Einstein-Gauss-Bonnet gravity (4DEGBG) coupled to non-linear gauge theory containing F2 term. Part of the importance of using a non-trivial 4D theory of Gauss-Bonnet gravity is that it is proven the absence of the Ostrogradsky instability was formulated in Glavan and Lin (2020) [26] and then regularized 4DEGBG theory was obtained in Hennigar et al. (2020) [45] and Fernandes et al. (2020) [49] as well as this theory gains many attentions because of its important finding for black hole physics. We therefore also study some properties of this solution such as temperature, specific heat, shadow and quasinormal modes. Our results here show that a confining charge f gives a significant contribution to the shadow of the black hole as well as quasinormal modes frequencies.

正则化4维Einstein-Gauss-Bonnet引力的标量-张量描述中具有限制电位的黑洞

在本文中,我们分析地提出了正则化 4 维爱因斯坦-高斯-博内引力 (4DEGBG) 与非线性规范理论耦合的标量张量描述的精确限制带电黑洞解,其中包含 -F2学期。使用Gauss-Bonnet 引力的非平凡4D理论的部分重要性在于,证明不存在 Ostrogradsky 不稳定性是在 Glavan 和 Lin (2020) [26] 中制定的,然后在 Hennigar 中获得了正则化的 4DEGBG 理论等。(2020) [45] 和费尔南德斯等人。(2020) [49] 以及该理论因其对黑洞物理学的重要发现而受到许多关注。因此,我们还研究了该解决方案的一些属性,例如温度、比热、阴影和准正规模式。我们的结果表明,限制电荷f对黑洞的阴影以及准正规模式频率做出了重大贡献。
