论文摘要
最近，一些实验观察到与标准模型（SM）的预测有重大冲突的结果。 LSND和MINIBOONE（MB）的两个中微子实验报告了类似电子的信号超过背景。 Brookhaven和Fermilab Muon $ g-2 $ Collaborations都测量了此参数的值，尽管彼此一致，但与SM矛盾。最近，CDF II合作报道了对$ W $ -BOSON质量的精确度量，该质量与SM预测发生了巨大冲突。值得寻求可能基本所有四个异常的新物理学。在这样的追求中，中微子实验可能起着至关重要的作用，因为一旦寻求对这些异常的常见解决方案，LSND和MB由于其高度限制性的要求和观察到的最终状态，有助于极大地范围缩小对$ w $ w $ smos和muon $ g-2 $ g-2 $ g-2 $ vicrepance becrepancies的多样性的范围。根据这一点，较早的工作表明，LSND，MB和MUON $ G-2 $结果可以在SM的标量扩展的背景下被理解，该量子符合第二个Higgs Doublet和Dark Sector Singlet。我们表明，同一模型会导致对$ W $质量的贡献，这与最近的CDF II测量相一致。虽然LSND，MB拟合和Muon $ G-2 $结果有助于确定模型中轻标度的质量，但斜参数的计算$ s $和$ t $确定了较重的伪caudsoscalar允许的质量范围，并获得了带电的Higgs支持器以及有效的Weinberg角度以及其新范围。
In recent times, several experiments have observed results that are in significant conflict with the predictions of the Standard Model (SM). Two neutrino experiments, LSND and MiniBooNE (MB) have reported electron-like signal excesses above backgrounds. Both the Brookhaven and the Fermilab muon $g-2$ collaborations have measured values of this parameter which, while consistent with each other, are in conflict with the SM. Recently, the CDF II collaboration has reported a precision measurement of the $W$-boson mass that is in strong conflict with the SM prediction. It is worthwhile to seek new physics which may underly all four anomalies. In such a quest, the neutrino experiments could play a crucial role, because once a common solution to these anomalies is sought, LSND and MB, due to their highly restrictive requirements and observed final states, help to greatly narrow the multiplicity of new physics possibilities that are otherwise open to the $W$ mass and muon $g-2$ discrepancies. Pursuant to this, earlier work has shown that LSND, MB and the muon $g-2$ results can be understood in the context of a scalar extension of the SM which incorporates a second Higgs doublet and a dark sector singlet. We show that the same model leads to a contribution to the $W$ mass which is consistent with the recent CDF II measurement. While the LSND, MB fits and the muon $g-2$ results help determine the masses of the light scalars in the model, the calculation of the oblique parameters $S$ and $T$ determines the allowed mass ranges of the heavier pseudoscalar and the charged Higgs bosons as well as the effective Weinberg angle and its new range.
