| Abstract: A search is presented for charged Higgs bosons in the $\mathrm{H}^{\pm} \to \tau^{\pm}\nu_\tau$ decay mode in the hadronic final state and in final states with an electron or muon. The search is based on proton-proton collision data recorded by the CMS experiment in 2016 at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. The results agree with the background expectation from the standard model. Upper limits at 95% confidence level are set on the production cross section times branching fraction to $\tau^{\pm}\nu_\tau$ for an $ \mathrm{H}^{\pm}$ in the mass range of 80 GeV to 3 TeV, including the region near the top quark mass. The observed limit ranges from 6 pb at 80 GeV to 5 fb at 3 TeV. The limits are interpreted in the context of the minimal supersymmetric standard model ${m_{\mathrm{h}}^\text{mod-}}$ scenario. | ||

Figure 1:
Leading order diagrams describing charged Higgs boson production. Double-resonant top quark production (left) is the dominant process for light ${\mathrm {H}^{\pm}}$, whereas the single-resonant top quark production (middle) dominates for heavy ${\mathrm {H}^{\pm}}$ masses. For the intermediate region (${{m_{{\mathrm {H}} ^\pm}} \sim {m_{{\mathrm {t}}}}}$), both production modes and their interplay with the nonresonant top quark production (right) must be taken into account. Charge-conjugate processes are implied. |

| Summary |
| A search is presented for charged Higgs bosons decaying as ${ \mathrm{H}^{\pm} \to \tau^{\pm} \nu_{\tau} }$, using events recorded by the CMS experiment in 2016 at a center-of-mass energy of 13 TeV. Transverse mass distributions are reconstructed in hadronic and leptonic final states and are found to agree with the standard model expectation. Upper limits for the product of the ${ \mathrm{H}^{\pm} }$ production cross section and the branching fraction to ${ \tau^{\pm} \nu_{\tau} }$ are set at 95% confidence level for an ${ \mathrm{H}^{\pm} }$ mass ranging from 80 GeV to 3 TeV, including the range close to the top quark mass. The observed limit ranges from 6 pb at 80 GeV to 5 fb at 3 TeV. The results are interpreted as constraints in the parameter space of the minimal supersymmetric standard model ${m_{\mathrm{h}}^\text{mod-}}$ benchmark scenario. In this scenario, all $ \tan\beta $ values from 1 to 60 are excluded for charged Higgs boson masses up to 160 GeV. |
