小希格斯模型在LHC和ILC上的鉴别

Little Higgs Model Discrimination at the LHC and ILC

Jurgen Reuter

摘要:

我们提出了一种方法来区分小希格斯模型的两个基本变体,产品组和简单组模型,在下一代的对撞机。它依赖于小希格斯模型中存在的轻赝标量粒子(赝轴子)与Z和希格斯玻色子的特殊耦合,这只存在于简单群模型中。我们讨论了对撞机现象的赝轴子在存在这样的耦合在大型强子对撞机,在那里的希格斯粒子或赝轴子的共振生产和衰变引起的耦合可以观察到的参数空间。所有允许的参数范围,包括在LHC中可观测性有限的区域,都由未来的ILC覆盖,其中双标量产生将是寻找的黄金通道。

英文摘要:

We propose a means to discriminate between the two basic variants of Little Higgs models, the Product Group and Simple Group models, at the next generation of colliders. It relies on a special coupling of light pseudoscalar particles present in Little Higgs models, the pseudoaxions, to the Z and the Higgs boson, which is present only in Simple Group models. We discuss the collider phenomenology of the pseudoaxion in the presence of such a coupling at the LHC, where resonant production and decay of either the Higgs or the pseudoaxion induced by that coupling can be observed for much of parameter space. The full allowed range of parameters, including regions where the observability is limited at the LHC, is covered by a future ILC, where double scalar production would be a golden channel to look for.
