AI中文摘要：
本工作中，我们评估了重顶伴侣粒子T的衰变宽度和分支比，并在Bestest Little Higgs模型（BLHM）框架下，对其在μ子对撞机上的成对产生和关联产生进行了全面的唯象学研究。BLHM为解决粒子物理标准模型（SM）中的精细调节问题提供了一种有吸引力且自然的机制。在对顶伴侣粒子T的研究中，我们考虑了产生过程μ⁺μ⁻→(γ,Z,Z',h,H)→T$\bar{T}$和μ⁺μ⁻→(γ,Z,Z',h,H)→$\bar{t}$T + t$\bar{T}$，并探索了μ子对撞机的不同质心系能量，以对感兴趣过程的产生截面进行数值分析。我们的结果表明，成对产生是在未来μ子对撞机上探测BLHM顶伴侣粒子最具前景的道。
英文摘要：
In this work, we evaluate the decay widths and branching ratios of the heavy top partner $T$, and perform a comprehensive phenomenological study of its pair and associated production at a muon collider within the framework of the Bestest Little Higgs Model (BLHM). The BLHM provides an attractive and natural mechanism for addressing the fine-tuning problem in the Standard Model (SM) of particle physics. In our study of the top partner $T$, we consider the production processes $μ^{+} μ^{-} \to (γ, Z, Z', h, H) \to T \bar{T}$ and $μ^{+} μ^{-} \to (γ, Z, Z', h, H)\to \bar{t}T+ t \bar{T}$, and we explore different center-of-mass energies of the muon collider to perform our numerical analysis of the production cross sections for the processes of interest. Our results show that pair production is the most promising channel for probing the top partner of the BLHM at a future muon collider.
