论文摘要

最近,有人指出,可以通过风味侵略轴承粒子(ALP)同时解释电子和元素G-2差异。我们表明,MUON G-2所青睐的参数区域已经被Muonium-Antimuon振荡绑定所排除。相反,当ALP重于1.5 GEV时,电子G-2的g-2可以与该结合一致。我们建议在Belle II实验中搜索相同和同一味的Lepton对和前后淡淡的Muon不对称的签名。

Recently, it was pointed out that the electron and muon g-2 discrepancies can be explained simultaneously by a flavor-violating axion-like particle (ALP). We show that the parameter regions favored by the muon g-2 are already excluded by the muonium-antimuonium oscillation bound. In contrast, those for the electron g-2 can be consistent with this bound when the ALP is heavier than 1.5 GeV. We propose to search for a signature of the same-sign and same-flavor lepton pairs and the forward-backward muon asymmetry to test the model at the Belle II experiment.
