We construct a field theoretical toy model for dilatonic matter using the five-dimensional Kaluza-Klein theory in the compactified approach. Kaluza’s ideas and basic aspects of compactification are examined in order to find an action with well-defined sectors. Through linearization of gravity sector, we obtain the propagators and interactions that allow to calculate differential cross sections at tree–level. We study some processes between photons and Kaluza-Klein particles, associated with the first massive mode of the scalar field. Finally, we make some discussion about possible applications and extensions of this model.

Kaluza-Klein Dilatonic问题：简化的玩具模型

我们采用压实方法，使用五维Kaluza-Klein理论构造了一个用于膨胀问题的野外理论玩具模型。审查了卡鲁扎的思想和紧缩的基本方面，以便找到具有明确定义的部门的行动。通过重力扇形的线性化，我们获得了传播子和相互作用，可以计算树级的微分横截面。我们研究了光子与Kaluza-Klein粒子之间的一些过程，与标量场的第一个大规模模式有关。最后，我们讨论该模型的可能应用和扩展。
