论文摘要
轴子弱重力猜想预测了激体群的存在,其作用小于其在适当单位中的电荷。我们表明,如果我们对较高的导数校正对二元性限制进行二元性约束,则可以满足猜想,此外还可以通过单位性,分析性和紫外线散射振幅的位置进行阳性范围。另一方面,如果我们仅假设阳性界限,则不会遵循猜想。这是一个例子,其中弱重力猜想的推导需要比散射幅度的一致性更详细的紫外线信息。
The axionic weak gravity conjecture predicts the existence of instantons whose actions are less than their charges in appropriate units. We show that the conjecture is satisfied for the axion-dilaton-gravity system if we assume duality constraints on the higher derivative corrections in addition to positivity bounds which follow from unitarity, analyticity, and locality of UV scattering amplitudes. On the other hand, the conjecture does not follow if we assume the positivity bounds only. This presents an example where derivation of the weak gravity conjecture requires more detailed UV information than the consistency of scattering amplitudes.
