论文摘要
我们使用有效的场理论方法研究了强烈的一阶电子相变。具有较高维操作员的有限数量截断的标准有效场理论在典型的参数空间中失败,在该空间中,实现强一阶相变的典型参数空间,因为它无法描述超出标准模型以外的新物理学的非偶联量子效应。为了参数化非耦合量子效应,我们采用了几乎对齐的Higgs有效理论,其中Higgs电位通过Coleman-Weinberg类似形式进行参数化。通过有限的温度校正扩展此框架,我们研究了实现强一阶相变的参数空间,并估算了相变时产生的重力波。
We investigate the strongly first-order electroweak phase transition using an effective field theoretical approach. The standard effective field theory with finite number truncation of higher dimensional operators fails in the typical parameter space where the strongly first-order phase transition is realized because it cannot describe the non-decoupling quantum effect of new physics beyond the standard model. To parameterize the non-decoupling quantum effect, we employ the nearly aligned Higgs effective theory in which the Higgs potential is parameterized by a Coleman-Weinberg like form. Extending this framework with finite temperature corrections, we study the parameter space for realizing the strongly first-order phase transition, and estimate the gravitational wave produced at the phase transition.
