Two-Higgs-doublet models in light of current experiments: a brief review

Understand

We briefly survey several typical CP-conserving two-Higgs-doublet models (2HDMs) in light of current experiments.

• First we derive the masses and couplings of the mass eigenstates from the Lagrangians.
• Then we analyze the constraints from theory and oblique electroweak parameters.
• Finally, we delineate the status of 2HDM in light of the LHC searches, the dark matter detections and the muon $g-2$ measurement.
