我们研究了在一类由多个高维规范场产生的稳健暴胀模型中，化学势机制在宇宙对撞机物理中的实现。滚动的暴胀子背景对应于额外维度中的电场，带电粒子通过类似施温格机制的方式产生，而中性粒子则可通过非最小相互作用产生。我们证明，在这两种情况下，重于暴胀哈勃尺度的粒子都可以产生，且不会受到玻尔兹曼抑制。特别地，带电卡鲁扎-克莱因激发可通过最小规范相互作用产生。我们构建了符合理论与实验约束的此类现实模型。
英文摘要
We study the realization of the chemical potential mechanism in cosmological collider physics in a robust class of inflationary models arising from multiple higher-dimensional gauge fields. The rolling inflaton background corresponds to an electric field in the extra dimension in which charged particles are produced analogously to the Schwinger mechanism, while neutral particles can be produced through non-minimal interactions. We show that particles heavier than the inflationary Hubble scale can be created without Boltzmann suppression in both cases. In particular, charged Kaluza-Klein excitations can be created through minimal gauge interactions. We construct realistic models along these lines consistent with both theoretical and experimental constraints.
