Search for charged Higgs bosons decaying via H± → τ±ν in fully hadronic final states using pp collision data at √s = 8 TeV with the ATLAS detector

Popis výsledku v původním jazyce

The results of a search for charged Higgs bosons decaying to a τ lepton and a neutrino, H± → τ± ν, are presented. The analysis is based on 19.5 fb−1 of proton-proton collision data at s√ = 8 TeV collected by the ATLAS experiment at the Large Hadron Collider. Charged Higgs bosons are searched for in events consistent with top-quark pair production or in associated production with a top quark, depending on the considered H± mass. The final state is characterised by the presence of a hadronic τ decay, missing transverse momentum, b-tagged jets, a hadronically decaying W boson, and the absence of any isolated electrons or muons with high transverse momenta. The data are consistent with the expected background from Standard Model processes. A statistical analysis leads to 95% confidence-level upper limits on the product of branching ratios ℬ(t → bH±) × ℬ(H± → τ± ν), between 0.23% and 1.3% for charged Higgs boson masses in the range 80-160GeV.n
