{"arxiv_id":"2010.02799","title":"Power-aligned 2HDM: a correlative perspective on $(g-2)_{e,\\mu}$","abstract":"With the hypothesis of minimal flavor violation, we find that there exists a power-aligned relation between the Yukawa couplings of the two scalar doublets in the two-Higgs-doublet model with Hermitian Yukawa matrices. Within such a power-aligned framework, it is found that a simultaneous explanation of the anomalies observed in the electron and muon anomalous magnetic moments can be reached with TeV-scale quasi-degenerate Higgs masses, and the resulting parameter space is also phenomenologically safer under the B-physics, $Z$ and $\\tau$ decay data, as well as the current LHC bounds. Furthermore, the flavor-universal power that enhances the charged-lepton Yukawa couplings prompts an interesting correlation between the two anomalies, which makes the model distinguishable from the (generalized) linearly aligned and the lepton-specific two-Higgs-doublet models that address the same anomalies but in a non-correlative manner, and hence testable by future precise measurements.","primary_cat":"hep-ph","cross_cats":["hep-ex"],"submitted_at":"2020-10-06T15:12:15+00:00","latest_version":3,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":"CONDITIONAL","confidence":"MODERATE","one_line_summary":"Power-aligned Yukawa couplings in a Hermitian two-Higgs-doublet model can simultaneously fit the electron and muon g-2 anomalies with TeV-scale quasi-degenerate Higgs masses, predicting a correlation between the two.","novelty_score":6.0,"correctness_risk":"medium","formal_verification":"none","upvotes":0,"downvotes":0,"pith_score":0.0,"inbound_count":13,"_links":{"html":"https://pith.science/paper/2010.02799","verdict":"/api/v1/verdicts/2010.02799"}}
