Abstract: A search for charged Higgs bosons decaying into a top and a bottom quark-antiquark pair in the fully hadronic final state is presented. The analysis uses LHC proton-proton collision data recorded with the CMS detector in 2016 at $\sqrt{s} = $ 13 TeV, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. No significant deviation above the expected background is observed. Model-independent upper limits at 95% confidence level are set on the charged Higgs boson production cross section times branching fraction in two scenarios. For production in association with a top quark, limits of 21.3 to 0.007 pb are calculated for charged boson masses in the range 200 GeV to 3 TeV. Combination with data from a search in the leptonic final states results in improved limits of 9.25 to 0.005 pb. The complementary s-channel production of a charged Higgs boson is investigated in the mass range 800 GeV to 3 TeV and the corresponding upper limits are 4.5 to 0.023 pb. These results are interpreted in different minimal supersymmetric extensions of the standard model.
