论文摘要
新颖的$ 4D $ EINSTEIN-GAUSS-BONNET（EGB）重力引起了极大的关注。在本文中，我们研究了针对带有测试带电的标量场和测试带电粒子的新型$ 4D $带电的EGB黑洞的弱宇宙审查猜想的有效性。对于测试带电的场散射过程，我们发现极端和近超级黑洞都不能过多。对于测试带电的颗粒注入，对于一阶，极端的黑洞不能被过度充电，而几乎卖出的$ 4D $充电的EGB黑洞可能会被摧毁。然而，对于第二阶，极端和近超额$ 4D $收费的EGB黑洞都可以被过度充电，以使高斯 - 骨网耦合常数为正；对于负高斯河网耦合常数，极端黑洞不能过多充电，并且弱宇宙审查猜想对近超级黑洞的有效性取决于高斯 - 骨网耦合常数。
Recent researches of the novel $4D$ Einstein-Gauss-Bonnet (EGB) gravity have attracted great attention. In this paper, we investigate the validity of the weak cosmic censorship conjecture for a novel $4D$ charged EGB black hole with test charged scalar field and test charged particle respectively. For the test charged field scattering process, we find that both extremal and near-extremal black holes cannot be overcharged. For the test charged particle injection, to first order, an extremal black hole cannot be overcharged while a near-extremal $4D$ charged EGB black hole can be destroyed. To second order, however, both extremal and near-extremal $4D$ charged EGB black holes can be overcharged for positive Gauss-Bonnet coupling constant; for negative Gauss-Bonnet coupling constant, an extremal black hole cannot be overcharged and the validity of the weak cosmic censorship conjecture for a near-extremal black hole depends on the Gauss-Bonnet coupling constant.
