Title: Search for a charged Higgs boson in pp collisions at √s = 8 TeV

Our 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. Furthermore, a model-independent upper limit on the product branching fraction B(t→H±b)B(H±→τ±ντ)=1.2-0.15% is obtained in the mass range m = 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 ±→tb)=1, an upper limit on σ(pp → t(b)H±) of 2.0–0.13 pb is setmore » for m = 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.« less
