标题： Explaining electron and muon $g-2$ anomalies in an Aligned 2-Higgs Doublet Model with Right-Handed Neutrinos

摘要： 我们用包含右旋中微子的对齐2-希格斯二重态模型来解释目前在测量电子（$a_e$）和缪子（$a_\mu$）异常磁矩的各种数据样本中存在的异常。这种解释由一环和二环拓扑结构驱动，在这些结构中，一个非常轻的CP奇性中性希格斯态（$A$）对$a_\mu$有显著贡献，但对$a_e$几乎没有贡献，从而使新物理修正的符号在前一种情况下相对于后一种情况发生反转，在后一种情况下，主要贡献来自带电希格斯玻色子（$H^\pm$）和质量处于弱电尺度的重中微子。 对于解释上述异常的新物理模型的参数空间区域，我们还预测了一个几乎无背景的明确信号，该信号由$H^\pm A$产生，随后是希格斯玻色子衰变产生多$\tau$最终态，这可以在大型强子对撞机上进行研究。 显示英文摘要

摘要： We explain anomalies currently present in various data samples used for the measurement of the anomalous magnetic moment of electron ($a_e$) and muon ($a_\mu$) in terms of an Aligned 2-Higgs Doublet Model with right-handed neutrinos. The explanation is driven by one and two-loop topologies wherein a very light CP-odd neutral Higgs state ($A$) contributes significantly to $a_\mu$ but negligibly to $a_e$, so as to revert the sign of the new physics corrections in the former case with respect to the latter, wherein the dominant contribution is due to a charged Higgs boson ($H^\pm$) and heavy neutrinos with mass at the electroweak scale. For the region of parameter space of our new physics model which explains the aforementioned anomalies we also predict an almost background-free smoking-gun signature of it, consisting of $H^\pm A$ production followed by Higgs boson decays yielding multi-$\tau$ final states, which can be pursued at the Large Hadron Collider.
