论文摘要

我们指出,Leptonic偶极矩和Lepton成对的高能横截面中的重大物理贡献与Higgs玻色子和光子无关。特别是,我们证明了在几个TEV的质量中心能量运行的MUON对撞机,可以通过研究Mu+ Mu--> H Gamma等高能过程来对MUON G-2的新物理进行独特的测试。这项高能量测试对于阐明长期存在的MUON G-2异常非常重要,因为它不受进入MUON G-2的当前低能测定的强化和实验性不确定性的影响。此外,我们表明,在MUON电偶极矩上的电流可以通过三个数量级改进,低至几个x 10^-22 e cm。

We point out that heavy new physics contributions in leptonic dipole moments and high-energy cross-sections of lepton pairs into Higgs bosons and photons are connected model-independently. In particular, we demonstrate that a muon collider, running at center-of-mass energies of several TeV, can provide a unique test of new physics in the muon g-2 through the study of high-energy processes such as mu+ mu- -> h gamma. This high-energy test would be of the utmost importance to shed light on the long-standing muon g-2 anomaly as it is not affected by the hadronic and experimental uncertainties entering the current low-energy determination of the muon g-2. Furthermore, we show that the current bound on the muon electric dipole moment can be improved by three orders of magnitude, down to few x 10^-22 e cm.
