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~\mathrm{TeV}

, corresponding to an integrated luminosity of

35.9~\mathrm{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~\mathrm{pb}

are calculated for charged boson masses in the range

200~\mathrm{GeV}

to

3~\mathrm{TeV}

. Combination with data from a search in the leptonic final states results in improved limits of 9.25 to

0.005~\mathrm{pb}

. The complementary s-channel production of a charged Higgs boson is investigated in the mass range

800~\mathrm{GeV}

to

3~\mathrm{TeV}

and the corresponding upper limits are 4.5 to

0.023~\mathrm{pb}

. These results are interpreted in different minimal supersymmetric extensions of the standard model.
