μ介子对撞机上μ介子g-2的高能前沿

High-energy frontier of the muon g-2 at a muon collider

Paride Paradisi, Olcyr Sumensari, Alessandro Valenti

摘要:

长期存在的μ介子g-2反常现象可以用重的新物理粒子通过手征增强的贡献来解释。最近有人提出,一个运行在质心能量为几个TeV的μ子对撞机可以通过研究高能过程(如mu+ mu-> h γ),以独立于模型的方式测试这些新的物理场景。在这项工作中,我们验证了这些发现,有效场论的基础上,通过考虑选定的可重正化简化模型,并通过计算这一循环的过程中充分的一般性。此外,我们探索直接和间接的高能搜索的相互作用,以确定适应μ介子g-2异常的潜在新物理模型的细节。

英文摘要:

The long-standing muon g-2 anomaly can be explained by heavy new physics particles through chirally enhanced contributions. It has been recently proposed that a muon collider running at center-of-mass energies of several TeV could test these new physics scenarios in a model-independent way, through the study of high-energy processes such as mu+ mu- --> h gamma. In this work, we validate these findings, based on effective field theories, by considering selected renormalizable simplified models and by computing this one-loop process in full generality. Furthermore, we explore the interplay of direct and indirect high-energy searches to pin down the details of the underlying new physics model accommodating the muon g-2 anomaly.
