从sine-Gordon到平坦和弯曲时空中的无真空系统

From sine-Gordon to vacuumless systems in flat and curved spacetimes

D. Bazeia, D. C. Moreira

摘要:

在这项工作中,我们开始从希格斯原型模型引入一个新的模型,这使得一个平稳的过渡系统之间的最小值和系统,支持没有最小值。我们实现这种可能性使用的变形过程,它允许获得的正弦戈登样模型,由一个真正的参数,产生一个家庭的模型,再现正弦戈登和所谓的无真空模型控制。我们还研究了与这些模型相关的厚膜情形,并研究了它们的稳定性和重整化群流。特别是,一个显示如何重力可以改变从5维扭曲几何与一个单一的额外维度的无限范围的传统5维闵可夫斯基几何。

英文摘要:

In this work we start from the Higgs prototype model to introduce a new model, which makes a smooth transition between systems with well located minima and systems that support no minima at all. We implement this possibility using the deformation procedure, which allows the obtention of a sine-Gordon-like model, controlled by a real parameter that gives rise to a family of models, reproducing the sine-Gordon and the so-called vacuumless models. We also study the thick brane scenarios associated with these models and investigate their stability and renormalization group flow. In particular, one shows how gravity can change from the 5-dimensional warped geometry with a single extra dimension of infinite extent to the conventional 5-dimensional Minkowski geometry.
