论文摘要
在本文中，我们研究了重力诱导的较高维操作员对包含两个相互作用标量场的模型中真空稳定性问题的影响。作为一个框架，我们使用了应用于上述系统的弯曲时空有效场理论（CEFT），其中一个标量很重。整合了重型标量后，我们将标准的欧几里得方法用于获得的CEFT。除了分析标准运算符的影响之外，例如非最小耦合与重力耦合以及对标量场电位的尺寸六个贡献之外，我们还研究了很少讨论的尺寸对动力学术语的贡献，而新的重力对标量Quartic Quartic Quartic Selfteractact进行了贡献。
In this article we investigated the influence of the gravity induced higher dimensional operators on the issue of vacuum stability in a model containing two interacting scalar fields. As a framework we used the curved spacetime Effective Field Theory (cEFT) applied to the aforementioned system in which one of the scalars is heavy. After integrating out the heavy scalar we used the standard Euclidean approach to the obtained cEFT. Apart from analyzing the influence of standard operators like the non-minimal coupling to gravity and the dimension six contribution to the scalar field potential, we also investigated the rarely discussed dimension six contribution to the kinetic term and the new gravity induced contribution to the scalar quartic self-interaction.
