Description
We show the implications of the muon anomalous magnetic moment for two-Higgs-doublet models (2HDMs), which are classified according to imposed symmetries and their resulting Yukawa sector. In the minimal setup, the muon g-2 can be accommodated by the type-X (leptophilic) 2HDM, flavor-aligned 2HDM (FA2HDM), muon-specific 2HDM (mu2HDM), and mu-tau-flavor-violating 2HDM. We clarify the available parameter spaces of these 2HDMs and investigate how to probe the remaining parameter regions in future experiments. In particular, we find that, the remaining parameter region of the FA2HDM is almost equivalent to that of the type-X 2HDM, and they are excluded by the latest collider searches for the muon g-2 solution.
