无碰撞痕迹的强电弱相变

Strong electroweak phase transitions without collider traces

A. Ashoorioon, T. Konstandin

摘要:

我们讨论的问题,如果即将到来的一代对撞机和低能量实验可以成功地探测的性质的电弱相变。特别是,我们感兴趣的相变足够强的电弱重子生成,甚至生产的引力辐射可观察到的大爆炸观测。作为一个明确的例子,我们提出了一个分析单态扩展的标准模型。我们专注于参数空间中的区域,该模型的发展没有显着的偏差,其低能量的现象从标准模型。然而,这类模型可以发展出非常强的相变。

英文摘要:

We discuss the question if the upcoming generation of collider and low-energy experiments can successfully probe the nature of the electroweak phase transition. In particular, we are interested in phase transitions strong enough for electroweak baryogenesis or even for a production of gravitational radiation observable by the Big Bang Observer. As an explicit example, we present an analysis in a singlet extension of the Standard Model. We focus on the region in parameter space where the model develops no significant deviation in its low energy phenomenology from the Standard Model. Nevertheless, this class of models can develop a very strong phase transition.
