论文摘要
许多新的物理场景都包含超轻型标量，这些状态比模型中的任何其他大粒子都完全无质量或轻得多。轴和马诺克斯构成了这种类型粒子的良好动机示例。在这项工作中，我们探讨了低能发酵性可观察物中这些状态的现象学。在采用了包括标量和伪尺度相互作用的模型独立方法之后，我们简要讨论了对角线耦合的当前限制，并考虑直接生产超级标量$ ϕ $的过程，例如，$μ\ to $μ\ to e \，ϕ $或作为介导的过程，或作为$ the $ the $ the $ cyustiatiation $。还研究了对带电瘦小的磁力和电力矩的贡献。
Many new physics scenarios contain ultralight scalars, states which are either exactly massless or much lighter than any other massive particle in the model. Axions and majorons constitute well-motivated examples of this type of particle. In this work, we explore the phenomenology of these states in low-energy leptonic observables. After adopting a model independent approach that includes both scalar and pseudoscalar interactions, we briefly discuss the current limits on the diagonal couplings to charged leptons and consider processes in which the ultralight scalar $ϕ$ is directly produced, such as $μ\to e \, ϕ$, or acts as a mediator, as in $τ\to μμμ$. Contributions to the charged leptons magnetic and electric moments are studied as well.
