论文摘要
我们研究$ e $，$μ$和$τ$ leptons的异常磁矩和违反风味的过程。我们使用数据驱动的方法来研究当前数据对具有SPIN-0标量和SPIN-1/2 fermion字段的一类模型参数的含义。我们比较两个不同的情况，这些情况具有或没有内置的取消机制。我们的发现如下。手性相互作用无法产生足够大的$ΔA_e$和$ΔA_μ$来适应实验结果。可观的$ΔA_e$和$ΔA_μ$可以从非手续相互作用产生，但它们不是从同一来源造成的。 $μ\ toeγ$衰减的上限给出了$μ\ E $转换的光子企鹅贡献的最严重限制，但是考虑到将来的实验敏感性，情况可能会发生变化。 $ z $ - 销售图可以比$μ\ to e $ transitions的光子企鹅图更好地限制手性互动。在大多数参数空间中，$μ\ to 3e $衰减的盒子贡献是转向的。 In $τ\to e$ $(μ)$ transitions, the present $τ\to eγ$ $(μγ)$ upper limit constrains the photonic penguin contribution better than the $τ\to 3 e$ $(3μ)$ upper limit, and $Z$-penguin amplitudes constrain chiral interaction better than photonic penguin amplitudes. $τ\至3e $和$τ\至3μ$衰减的盒子贡献可以与$ z $ -Penguin的贡献相提并论。 $τ^ - \ to e^ - μ^+ e^ - $和$τ^ - \toμ^ - e^+μ^ - $ $ ration $ to $τ\ toeγ$，$μ\ toeγ$和$°\ toμγ$，$μ\ toμγ$，$μ，$μ，$μ\ toeγ$上限。我们比较了当前的实验上限，未来的敏感性以及各种MUON和TAU LFV过程的界限。
We study anomalous magnetic moments and flavor violating processes of $e$, $μ$ and $τ$ leptons. We use a data driven approach to investigate the implications of the present data on the parameters of a class of models, which has spin-0 scalar and spin-1/2 fermion fields. We compare two different cases, which has or does not have a built-in cancelation mechanism. Our findings are as following. Chiral interactions are unable to generate large enough $Δa_e$ and $Δa_μ$ to accommodate the experimental results. Sizable $Δa_e$ and $Δa_μ$ can be generated from non-chiral interactions, but they are not contributed from the same source. The upper limit of $μ\to eγ$ decay gives the most severe constraints on photonic penguin contributions in $μ\to e$ transitions, but the situation may change in considering future experimental sensitivities. The $Z$-penguin diagrams can constrain chiral interaction better than photonic penguin diagrams in $μ\to e$ transitions. In most of the parameter space, box contributions to $μ\to 3e$ decay are subleading. In $τ\to e$ $(μ)$ transitions, the present $τ\to eγ$ $(μγ)$ upper limit constrains the photonic penguin contribution better than the $τ\to 3 e$ $(3μ)$ upper limit, and $Z$-penguin amplitudes constrain chiral interaction better than photonic penguin amplitudes. Box contributions to $τ\to 3e$ and $τ\to 3μ$ decays can sometime be comparable to $Z$-penguin contributions. The $τ^-\to e^- μ^+ e^-$ and $τ^-\to μ^- e^+ μ^-$ rates are highly constrained by $τ\to eγ$, $μ\to eγ$ and $τ\to μγ$, $μ\to eγ$ upper limits, respectively. We compare the current experimental upper limits, future sensitivities and bounds from consistency on various muon and tau LFV processes.
