| Abstract: A search for heavy charged Higgs bosons decaying into W and Z bosons in pp collisions at $\sqrt{s} =$ 13 TeV is presented. The data sample corresponds to an integrated luminosity of 2.3 and 12.9 fb$^{-1}$ collected with the CMS detector during 2015 and 2016, respectively. Events are selected with three leptons, electrons and muons, two jets with large rapidity separation and high dijet mass, and moderate missing transverse energy. The observation agrees with the standard model prediction. Limits on the charged Higgs boson cross section times branching fraction are given as a function of the charged Higgs boson mass and interpreted in the context of Higgs triplet models. | ||

| Summary |
| We presented a search for heavy charged Higgs bosons decaying into W and Z bosons in pp collisions at $\sqrt{s} =$ 13 TeV. The data sample corresponds to an integrated luminosity of 15.2 fb$^{-1}$ collected with the CMS detector in 2015 and 2016. Events are selected with three leptons, electrons and muons, two jets with large rapidity separation and high dijet mass, and moderate missing transverse energy. The observation agrees with the standard model prediction. Limits on the charged Higgs boson cross section time branching fraction are given and interpreted in the context of Higgs triplet models. |
