We show that any new interaction resulting in a chirally enhanced contribution to the muon magnetic moment necessarily modifies the decay rate of the Higgs boson to muon pairs or generates the muon electric dipole moment. These three observables are highly correlated, and near future measurements of hμ+μ will carve an ellipse in the plane of dipole moments for any such model. Together with the future measurements of the electric dipole moment many models able to explain the muon g2 anomaly can be efficiently tested.

Muon 偶极矩的椭圆

我们表明,任何导致对 μ 子磁矩的手性增强贡献的新相互作用必然会改变希格斯玻色子对 μ 子对的衰变率或产生 μ 子电偶极矩。这三个可观测值高度相关,并且在不久的将来测量Hμ+μ将为任何此类模型在偶极矩平面上刻一个椭圆。连同未来对电偶极矩的测量,许多模型能够解释 μ 子G2个可以有效地测试异常。
