Kaluza-Klein模式的牛顿力与库仑力比较

Newton versus Coulomb for Kaluza-Klein modes

Karim Benakli, Carlo Branchina, Gaëtan Lafforgue-Marmet

AI总结:

本文通过计算圆周紧致化下引力与非引力树级振幅,比较牛顿力与库仑力,恢复弱引力猜想约束,并研究KK模式对产生及非最小耦合贡献。

摘要:

我们考虑一组在圆周上从$D+1$维到$D维时空的基本紧致化:首先针对纯广义相对论,然后存在标量场的情况下,先是自由标量场,再是标量场与Ricci标量的非最小耦合,最后是存在规范玻色子的情况。我们计算树级振幅,以比较一些引力与非引力振幅。这使我们能够在某些情况下恢复$U(1)$、膨胀子(dilatonic)和标量弱引力猜想的已知约束,并展示不同相互作用之间的相互影响。我们研究了不同维度下KK模式的对产生。我们还讨论了高维中标量场与Ricci标量的非最小耦合对这些振幅中某些贡献的影响。

英文摘要:

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.
