Search for charged Higgs bosons decaying to tau+nu in top-antitop events with the ATLAS detector at the LHC

The ATLAS collaboration has performed a model-independent search for charged Higgs bosons in decays of pair-produced to pquarks using 4.6/fb of proton-proton collisions at sqrt(s) = 7 TeV. The charged Higgs are assumed to decay exclusively to a tau lepton and its associated neutrino. Three different...

description The ATLAS collaboration has performed a model-independent search for charged Higgs bosons in decays of pair-produced to pquarks using 4.6/fb of proton-proton collisions at sqrt(s) = 7 TeV. The charged Higgs are assumed to decay exclusively to a tau lepton and its associated neutrino. Three different final states are considered. In the absence of any significant excess of events over Standard Model expectations, 95% C.L. upper limits of 0.5 to 0.1 are placed on the branching fraction of the top quark decaying into a charged Higgs and a b quark, for charged Higgs boson masses of 90 GeV to 160 GeV, respectively.
