Constraints on and future prospects for two-Higgs-doublet models in light of the LHC Higgs signal

Abstract

We update the constraints on Two-Higgs-Doublet Models of Type I and II discussed in arXiv:1405.3584 using the latest LHC measurements of the ∼ 125.5 GeV Higgs signal as of Summer 2014. We provide explicit comparisons of the results before and after the Summer 2014 ATLAS and CMS updates. Overall, the changes with respect to arXiv:1405.3584 are rather small; to a large extent this is due to the fact that both the ATLAS and the CMS updates of the γγ decay mode moved closer to SM expectations. *

Higgs potential and hidden light Higgs scenario in two Higgs doublet models

“…[36]. Similar comprehensive studies in other setup such as very light Higgs bosons [31] or the minimal supersymmetric standard model [37] were followed up.…”

“…To answer the question, we consider more extended constraints than in Ref. [36], particularly those from the LHC heavy Higgs searches. We classify the theoretical and phenomenological constraints into three categories: theoretical bounds, pre-LHC bounds, and LHC bounds.…”

“…contributions from the production of heavier Higgs bosons through their decay into H 0 [36,56], not by just limiting the FD signal strength value.…”

Electron/muon specific two Higgs doublet model ate+e−colliders

“…Current limits on sin(β − α) from Type-I models [4][5][6][7] are rather weak, corresponding to sin(β − α) > 0.85. These results are not based on the electron or muon couplings of the Higgs, and thus they would apply in this model as well.…”

LHC searches for theCP-odd Higgs boson with a jet substructure analysis

“…Refs. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] Often, one would interpret the lighter CP-even Higgs boson h as the one discovered at the LHC. In the context of the general 2HDM, each Higgs boson mass is actually free parameter before applying any constraint.…”
