Description
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(tto
{H}^{±}b)B({H}^{±}to {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 (ppto
t(b){H}^{±})B({H}^{±}to {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 (ppto
overline{t}(b){H}+)+σ (ppto
t(overline{b}){H}-) . Assuming B({H}^{±}to tb)=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. [Figure not available: see
