论文摘要
我们考虑了一组基本的压实，即$ d+1 $至$ d $ $ d $时空的尺寸：首先是纯正的相对性，然后在存在标量场的情况下，首先免费，然后在ricci stalcor上脱离最小的耦合，最后在仪表孔的情况下进行。我们计算树级振幅，以比较一些引力和非重力振幅。这使我们能够恢复$ u（1）$，dilatonic和scalial弱重力猜想的已知约束，并显示不同相互作用的相互作用。我们研究了不同维度的KK模式成对生产。我们还讨论了对标量字段中与RICCI标量的较高维度中非最小耦合的某些振幅的贡献。
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.
