Search for a light charged Higgs boson in top quark decays in pp collisions at √ s = 7 TeV
Results are presented on a search for a light charged Higgs boson that can be produced in the decay of the top quark t → H+b and which, in turn, decays into τ+νt. The analysed data correspond to an integrated luminosity of about 2 fb-1 recorded in protonproton collisions at √s = 7 TeV by the CMS exp...

| description | Results are presented on a search for a light charged Higgs boson that can be produced in the decay of the top quark t → H+b and which, in turn, decays into τ+νt. The analysed data correspond to an integrated luminosity of about 2 fb-1 recorded in protonproton collisions at √s = 7 TeV by the CMS experiment at the LHC. The search is sensitive to the decays of the top quark pairs tt̄ → H±W∓bb̄ and tt̄ → H ±H∓bb̄. Various final states have been studied separately, all requiring presence of a τ lepton from H+ decays, missing transverse energy, and multiple jets. Upper limits on the branching fraction B(t → H+b) in the range of 2-4% are established for charged Higgs boson masses between 80 and 160 GeV, under the assumption that B(H+ → τ+ντ) = 1. |
