论文摘要
我们解释了目前在各种数据样本中存在的异常情况，用于测量电子（$ a_e $）的异常磁矩（$ a_e $）和MUON（$a_μ$），以与右手中微子的对齐的2-Higgs Doublet模型相对。 The explanation is driven by one and two-loop topologies wherein a very light CP-odd neutral Higgs state ($A$) contributes significantly to $a_μ$ 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中微子具有质量的质量。对于我们新物理模型的参数空间区域，该区域解释了上述异常，我们还预测了几乎没有背景的吸烟枪签名，由$ h^\ pm组成，$ h^\ pm a $生产，随后是希格斯·波森（Higgs Boson）衰减，产生了多$ $ $τ$最终状态，可以在大型的Hadron Coller中追求。
We explain anomalies currently present in various data samples used for the measurement of the anomalous magnetic moment of electron ($a_e$) and muon ($a_μ$) 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 $a_μ$ 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-$τ$ final states, which can be pursued at the Large Hadron Collider.
