论文摘要
我们根据黑洞弱重力猜想（WGC）分析了对5D爱因斯坦 - 马克斯韦理论的四源校正的约束。我们计算出渐近平面5D带电溶液以及4D Kaluza-Klein压缩的极端质量的主要校正。发现后者的WGC边界被解释为4D二型黑洞，被发现严格强。当磁性磁力指电荷在5D中升至螺母的电荷时，我们认为WGC的逻辑也应适用于这些拓扑电荷，并导致对纯粹的重力理论的新约束。
We analyze the constraints on four-derivative corrections to 5d Einstein-Maxwell theory from the black hole Weak Gravity Conjecture (WGC). We calculate the leading corrections to the extremal mass of asymptotically flat 5d charged solutions as well as 4d Kaluza-Klein compactifications. The WGC bounds from the latter, interpreted as 4d dyonic black holes, are found to be strictly stronger. As magnetic graviphoton charge lifts to a NUT-like charge in 5d, we argue that the logic of the WGC should apply to these topological charges as well and leads to new constraints on purely gravitational theories.
