辐射μ子质量模型与$(g-2)_μ$

Radiative Muon Mass Models and $(g-2)_μ$

Michael J. Baker, Peter Cox, Raymond R. Volkas

摘要:

最近对希格斯介子耦合的测量首次直接探测了介子质量的产生。我们分类极小模型与一个循环的辐射质量机制,并表明基准模型与目前的实验结果是一致的。我们发现,这些模型是最好的探测$(g-2)_μ$的测量,即使考虑到希格斯粒子的测量精度预计在未来的对撞机。目前的$(g-2)_μ$异常,如果得到证实,可能是第一个提示,μ子质量有一个辐射的起源。

英文摘要:

Recent measurements of the Higgs-muon coupling are directly probing muon mass generation for the first time. We classify minimal models with a one-loop radiative mass mechanism and show that benchmark models are consistent with current experimental results. We find that these models are best probed by measurements of $(g-2)_μ$, even when taking into account the precision of Higgs measurements expected at future colliders. The current $(g-2)_μ$ anomaly, if confirmed, could therefore be a first hint that the muon mass has a radiative origin.
