标题： Newton versus Coulomb for Kaluza-Klein modes

摘要： 我们考虑了一组从 $D+1$ 到 $D$ 时空维度在圆上的基本紧化：首先针对纯广义相对论，然后在存在标量场的情况下，先自由标量场再非最小耦合到黎曼曲率标量，最后在存在规范玻色子的情况下。 我们计算了树级振幅以比较一些引力和非引力振幅。 这使我们在某些情况下恢复了已知的 $U(1)$、 稀释场 和标量弱引力猜想的约束，并展示了不同相互作用之间的关联。 我们研究了不同维度下KK模式的成对产生。 我们还讨论了高维标量场与黎曼曲率标量之间的非最小耦合对某些振幅的贡献。 显示英文摘要

摘要： We consider a set of elementary compactifications of $D+1$ to $D$ spacetime dimensions on a circle: first for pure general relativity, then in the presence of a scalar field, first free then with a non minimal coupling to the Ricci scalar, and finally in the presence of gauge bosons. We compute the tree-level amplitudes in order to compare some gravitational and non-gravitational amplitudes. This allows us to recover the known constraints of the $U(1)$, dilatonic and scalar Weak Gravity Conjectures in some cases, and to show the interplay of the different interactions. We study the KK modes pair-production in different dimensions. We also discuss the contribution to some of these amplitudes of the non-minimal coupling in higher dimensions for scalar fields to the Ricci scalar.
