| Özet |
| 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+ ν τ. The analysed data correspond to an integrated luminosity of about 2 fb− 1 recorded in protonproton collisions at by the CMS experiment at the LHC. The search is sensitive to the decays of the top quark pairs→ H±W∓ and→ H±H∓. 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+ ν τ)= 1. |
