摘要:

扩展标准模型的标量部分是探索超出标准模型物理的一种有说服力的方法。在本文中,我们研究了未来μ子对撞机中三双态模型的现象学。三双态模型的标量谱包括三个电中性标量玻色子、两个电荷标量玻色子以及一个电荷标量态对。我们专注于通过μ子-反μ子湮灭产生希格斯对的过程,研究中性标量态的产生和衰变过程,假设存在质量层次结构,其中标准模型样式的电中性标量是质量最轻的状态。我们分析了多个基准场景,导致b b b b和b b t t的最终状态,并在中心对撞能为√s=3 TeV的情况下进行了切片和计数分析。我们的结果表明,未来的μ子对撞机为探测扩展的希格斯扇区提供了一个敏感且有前景的环境,质量在200-400 GeV范围内的中性标量态在积分亮度为O(1-4 ab⁻¹)时可以以5σ显著性发现。

英文摘要:

Extending the scalar sector of the Standard Model is a well-motivated approach to exploring physics beyond the Standard Model. In this work, we investigate the phenomenology of the Three Higgs Doublet Model at a future muon collider. The scalar spectrum of the 3HDM comprises three CP-even Higgs bosons, two CP-odd Higgs bosons, and a pair of charged Higgs states. Focusing on Higgs pair production via muon-antimuon annihilation, we study the production and decay of neutral scalar states through the process $μ^+μ^- \to ϕ_i ϕ_j$, assuming a mass hierarchy in which the SM-like CP-even Higgs is the lightest state. We analyze several benchmark scenarios leading to $b\bar{b}b\bar{b}$ and $b\bar{b}t\bar{t}$ final states, and perform a cut-and-count analysis at a center-of-mass energy of $\sqrt{s}=3$ TeV. Our results demonstrate that a future muon collider provides a sensitive and promising environment to probe extended Higgs sectors, with neutral scalar states in the mass range of $200-400$ GeV being discoverable with $5σ$ significance for integrated luminosities of $\mathcal{O}(1-4 \ \mathrm{ab}^{-1})$.
