我们研究了量子效应对增强对称点（ESP）附近粒子产生的模量动力学的影响。我们专注于不可重正化的耦合之间的模量场和场，成为光在ESP。考虑到高维的相互作用，我们发现，粒子生产是显着的，在一个大的区域，这是甚至大于预期的区域，从一个重正化的相互作用。从平凡的绝热条件中找到这种可能性是可能的;然而，对粒子产生和运动场捕获的定量估计远非平凡。在本文中，我们详细研究粒子的产生和捕获，使用分析和数值计算，找到一个清晰和直观的结果，支持捕获在各种各样的理论。我们的研究表明，捕获驱动的非重整化的相互作用是可能的。这种可能性在以前的作品中没有考虑过。粒子物理学的一些唯象模型将被提及以补充讨论。
We study quantum effects on moduli dynamics arising from particle production near the enhanced symmetry point (ESP). We focus on non-renormalizable couplings between the moduli field and the field that becomes light at the ESP. Considering higher dimensional interaction, we find that particle production is significant in a large area, which is even larger than the area that is expected from a renormalizable interaction. It is possible to find this possibility from a trivial adiabatic condition; however the quantitative estimation of particle production and trapping of the field in motion are far from trivial. In this paper we study particle production and trapping in detail, using both the analytical and numerical calculations, to find a clear and intuitive result that supports trapping in a vast variety of theories. Our study shows that trapping driven by a non-renormalizable interaction is possible. This possibility has not been considered in previous works. Some phenomenological models of particle physics will be mentioned to complement discussion.
