极吸引子产生的光希格斯玻色子

Light Higgs Boson from a Pole Attractor

Oleksii Matsedonskyi, Marc Montull

摘要:

我们提出了一种在宇宙学驰豫框架内解释观察到的希格斯质量的新方法。它与其他扫描方案的主要区别在于扫描场具有非正则动力学项,其作用是在所需的希格斯质量值附近终止扫描。我们提出了一个具体的实现这一想法的两个新的单态场,一个扫描希格斯质量,另一个限制的时间窗口,其中扫描是可能的。在所提供的时间段内,由于粒子产生摩擦,在希格斯场接近标准模型值之后,扫描场没有显著地演变。

英文摘要:

We propose a new way of explaining the observed Higgs mass, within the cosmological relaxation framework. The key feature distinguishing it from other scanning scenarios is that the scanning field has a non-canonical kinetic term, whose role is to terminate the scan around the desired Higgs mass value. We propose a concrete realisation of this idea with two new singlet fields, one that scans the Higgs mass, and another that limits the time window in which the scan is possible. Within the provided time period, the scanning field does not significantly evolve after the Higgs field gets close to the Standard Model value, due to particle production friction.
