{"arxiv_id":"hep-ph/0510154","title":"Tree-unitarity bounds for THDM Higgs masses revisited","abstract":"We have reconsidered theoretical upper bounds on the scalar boson masses within the two-Higgs-doublet model (THDM), employing the well-known technical condition of tree-level unitarity. Our treatment provides a modest extension and generalization of some previous results of other authors. We present a rather detailed discussion of the solution of the relevant inequalities and offer some new analytic formulae as well as numerical values for the Higgs mass bounds in question. A comparison is made with the earlier results on the subject that can be found in the literature.","primary_cat":"hep-ph","cross_cats":[],"submitted_at":"2005-10-12T16:12:32+00:00","latest_version":2,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":"CONDITIONAL","confidence":"MODERATE","one_line_summary":"Tree-level unitarity implies that the charged, pseudoscalar, and heavy neutral Higgs masses in the two-Higgs-doublet model are bounded by about 712 GeV times a factor depending on the Z2-breaking parameter, with the lightest scalar bounded more tightly.","novelty_score":3.0,"correctness_risk":"medium","formal_verification":"none","upvotes":0,"downvotes":0,"pith_score":0.0,"inbound_count":27,"_links":{"html":"https://pith.science/paper/hep-ph/0510154","verdict":"/api/v1/verdicts/hep-ph/0510154"}}
