标题： Supersymmetric gauged U(1)$_{L_μ-L_τ}$ model for electron and muon $(g-2)$ anomaly

摘要： 最小的规范 U(1)$_{L_{\mu}-L_{\tau}}$模型可以为缪子异常磁矩提供额外的来源，然而同时容纳电子磁矩差异却很困难。 由于这些量之间的差异符号相对，似乎不太可能来自同一来源。 我们表明，一个超对称（SUSY）规范 U(1)$_{L_{\mu}-L_{\tau}}$模型可以在一个非常简单和直观的情景中同时容纳缪子和电子异常磁矩，而无需利用轻子味破坏。 在这种情景中，目前允许的参数空间受到最新LHC和各种低能实验数据的约束，例如最近的COHERENT数据、CCFR、Borexino、BaBaR、超新星等。 这些约束结合解释两种轻子磁矩的要求，导致第一代超轻子质量的上限、第二代超轻子质量的下限以及对新规范玻色子质量和耦合的允许范围的限制。 该方案可以在正在进行的COHERENT和Coherent CAPTAIN-Mills实验以及未来实验中进行探测，例如DUNE、BELLE-II等。 显示英文摘要

摘要： Minimal gauged U(1)$_{L_{\mu}-L_{\tau}}$ 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)$_{L_{\mu}-L_{\tau}}$ 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.
