作为$H/A$工厂的μ子对撞机

The Muon Collider as a $H/A$ factory

Estia Eichten, Adam Martin

摘要:

我们表明,μ子对撞机是理想的适合于研究重H/A标量,表兄弟的希格斯玻色子中发现的两个希格斯偶极子模型和超对称模型所需的。H/A的关键方面是:(1)它们很窄,但宽度质量比远远大于预期的μ子对撞机束能分辨率,(2)更大的μ子汤川允许有效的s通道产生。我们详细研究了一个具有代表性的自然超对称模型,H/A为1.5 Tev,$m_H$ - $m_A$ = 10 Gev.共振峰处的大事件率允许确定单个H和A共振参数(包括CP),并且衰变为电弱子提供了任何其他现有或计划的对撞机无法获得的丰富信息。

英文摘要:

We show that a muon collider is ideally suited for the study of heavy H/A scalars, cousins of the Higgs boson found in two-Higgs doublet models and required in supersymmetric models. The key aspects of H/A are: (1) they are narrow, yet have a width-to-mass ratio far larger than the expected muon collider beam-energy resolution, and (2) the larger muon Yukawa allows efficient s-channel production. We study in detail a representative Natural Supersymmetry model which has a 1.5 Tev H/A with $m_H$- $m_A$ = 10 Gev. The large event rates at resonant peak allow the determination of the individual H and A resonance parameters (including CP) and the decays into electroweakinos provides a wealth of information unavailable to any other present or planned collider.
