一种新的与μ子和质子耦合的标量玻色子可以同时解决质子半径之谜和μ子反常磁矩差异。通过各种测量，我们限制了该标量的质量及其与电子、μ子、中子和质子的耦合。在不对基础模型做出任何假设的情况下，这些约束以及解决这两个问题的要求将标量的质量限制在大约 100 keV 到 100 MeV 之间。我们在耦合恒定质量平面中确定了两个未探索的区域。讨论了未来潜在的实验及其对质量加权轻子耦合理论的影响。
A new scalar boson which couples to the muon and proton can simultaneously solve the proton radius puzzle and the muon anomalous magnetic moment discrepancy. Using a variety of measurements, we constrain the mass of this scalar and its couplings to the electron, muon, neutron, and proton. Making no assumptions about the underlying model, these constraints and the requirement that it solve both problems limit the mass of the scalar to between about 100 keV and 100 MeV. We identify two unexplored regions in the coupling constant-mass plane. Potential future experiments and their implications for theories with mass-weighted lepton couplings are discussed.
