abstract
A search for a charged Higgs boson H$^\pm$ decaying into a heavy neutral Higgs boson H and a W boson is presented. The analysis targets the H decay into a pair of tau leptons with at least one of them decaying hadronically and with an additional electron or muon present in the event. The search is based on proton-proton collision data recorded by the CMS experiment during 2016-2018 at $\sqrt{s}$ = 13 TeV, corresponding to an integrated luminosity of 138 fb$^{-1}$. The data are consistent with standard model background expectations. Upper limits at 95% confidence level are set on the product of the cross section and branching fraction for an H$^\pm$ in the mass range of 300-700 GeV, assuming an H with a mass of 200 GeV. The observed limits range from 0.085 pb for an H$^\pm$ mass of 300 GeV to 0.019 pb for a mass of 700 GeV. These are the first limits on H$^\pm$ production in the H$^\pm$ $\to$ HW$^\pm$ decay channel at the LHC.

Searching for charged Higgs bosons via $e^+ e^- \to H^\pm W^\mp S$ at the ILC
A detector-level Monte Carlo study shows that e+e- -> H± W∓ S in the type-X 2HDM could be discovered at the ILC with 500 GeV and 500 fb^-1.

Charged Higgs Search at Future Neutrino Telescope and Higgs Factory
Future lepton colliders can discover a charged Higgs below about half their energy, while multi-cubic-kilometer neutrino telescopes add complementary reach for heavier charged Higgs masses.

Probing one-loop--induced decay channel $H^\pm \to W^\pm\gamma$ in the Two Higgs Doublet Models at muon-TeV colliders
The one-loop decay H±→W±γ is re-derived in the general Rξ gauge and used to predict that a 3 TeV muon collider could see a charged Higgs signal, though the conclusion reports only 2 sigma for several benchmarks.

A comprehensive study of the charged Higgs boson in the two Higgs doublet type-II seesaw model
Charged Higgs production rates and 5-sigma discovery regions at a 3 TeV muon collider are computed for the 2HDMcT Type-III seesaw model, with the H1+ H1- channel exceeding the e+e- rate.
