论文摘要
深色光子量规耦合的微小值可以抑制其动力学混合与普通光子。我们指出，弱重力猜想预测，可能会出现新的自由度的紫外线临界值。特别是，为了适应Xenon1t报告的多余物质所必需的$ \ Mathcal {O}（10^{ - 15}）$的混合角度对应于低于$ \ MATHCAL {O}（100）$ TEV的新物理，因此在将来的圆形胶合器中可访问。我们表明，可能实现的实现是通过六个额外的额外尺寸和订单$ \ Mathcal {o}（100）$ tev的订单量表提供的。
Tiny values for gauge couplings of dark photons allow to suppress their kinetic mixing with ordinary photons. We point out that the Weak Gravity Conjecture predicts consequently low ultraviolet cut-offs where new degrees of freedom might appear. In particular, a mixing angle of $\mathcal{O}(10^{-15})$, required in order to fit the excess reported by XENON1T, corresponds to new physics below $\mathcal{O}(100)$ TeV, thus accessible at a Future Circular Collider. We show that possible realizations are provided by compactifications with six large extra dimensions and a string scale of order $\mathcal{O}(100)$ TeV.
