A bstract A search for a charged Higgs boson is performed with a data sample corresponding to an integrated luminosity of 19.7 ± 0.5 fb −1 collected with the CMS detector in proton-proton collisions at s = 8 ,TeV. The charged Higgs boson is searched for in top quark decays for m H ± < m t − m b , and in the direct production pp → t(b)H ± for m H ± > m t − m b . The H ± → τ ± ν τ and H ± → tb decay modes in the final states τ h +jets, μτ h , ℓ +jets, and ℓℓ ’ ( ℓ =e, μ ) are considered in the search. No signal is observed and 95% confidence level upper limits are set on the charged Higgs boson production. A model-independent upper limit on the product branching fraction ℬ t → H ± b ℬ H ± → τ ± ν τ = 1.2 − 0.15 % is obtained in the mass range m H ± = 80–160 GeV, while the upper limit on the cross section times branching fraction σ pp → t b H ± ℬ H ± → τ ± ν τ = 0.38 − 0.025 pb is set in the mass range m H + = 180–600 GeV. Here, σ (pp → t(b)H ± ) stands for the cross section sum σ pp → t ¯ b H + + σ pp → t b ¯ H − . Assuming ℬ H ± → t b = 1 , an upper limit on σ (pp → t(b)H ± ) of 2.0–0.13 pb is set for m H ± = 180–600 GeV. The combination of all considered decay modes and final states is used to set exclusion limits in the m H ±−tan β parameter space in different MSSM benchmark scenarios.
