论文摘要
最小的测量u（1）$ _ {l_μ-l_τ} $模型可以为muon异常磁矩提供其他源，但是很难串联电子磁矩中的差异。由于这些数量的差异之间的相对符号，它们似乎不太可能来自同一来源。我们表明，超对称（SUSY）测量的U（1）$ _ {l_μ-l_τ} $模型可以在非常简单，直观的情况下同时容纳MUON和电子异常的磁性矩，而不会利用Lepton侵犯Lepton风味。目前在这种情况下允许的参数空间受到最新的LHC和各种低能实验数据的约束量规玻色质量和耦合。该方案可以在正在进行的连贯和连贯的船长实验中进行探测，并在将来的实验，例如Dune，Belle-II等。
Minimal gauged U(1)$_{L_μ-L_τ}$ models can provide for an additional source for the muon anomalous magnetic moment however it is difficult to accommodate the discrepancy in the electron magnetic moment in tandem. Owing to the relative sign between the discrepancies in these quantities, it seems unlikely that they arise from the same source. We show that a supersymmetric (SUSY) gauged U(1)$_{L_μ-L_τ}$ model can accommodate both the muon and electron anomalous magnetic moments in a very simple and intuitive scenario, without utilizing lepton flavor violation. The currently allowed parameter space in this kind of a scenario is constrained from the latest LHC and various low energy experimental data,e.g., recent COHERENT data, CCFR, Borexino, BaBaR, supernova etc. These constraints, in conjunction with the requirement to explain both lepton magnetic moments, lead to an upper bound on the first generation slepton mass, a lower bound on the second generation slepton mass and constricts the allowed range for the new gauge boson mass and coupling. The scheme can be probed at the ongoing COHERENT and Coherent CAPTAIN-Mills experiments and at future experiments, e.g., DUNE, BELLE-II etc.
