电流LHC约束下的最小四维复合Higgs模型

Minimal 4D Composite Higgs Models Under Current LHC Constraints

Ethan Carragher, Daniel Murnane, Peter Stangl, Wei Su, Martin White, Anthony G. Williams

摘要:

我们提出了几个最小的复合希格斯模型的第一次收敛的全球拟合的初步结果。我们的拟合使用差分进化优化包$\texttt{Diver}$进行。考虑到各种物理约束,包括广泛的排斥边界上的重共振生产运行2的大型强子对撞机。作为拟合的副产品,我们分析了模型可行区域中最轻的新上型和下型共振的对撞机现象学,发现了一些可以在未来的对撞机搜索中探测的低质量共振。

英文摘要:

We present preliminary results of the first convergent global fits of several minimal composite Higgs models. Our fits are performed using the differential evolution optimisation package $\texttt{Diver}$. A variety of physical constraints are taken into account, including a wide range of exclusion bounds on heavy resonance production from Run 2 of the LHC. As a by-product of the fits, we analyse the collider phenomenology of the lightest new up-type and down-type resonances in the viable regions of our models, finding some low-mass resonances that can be probed in future collider searches.
