Abstract
A search for a charged Higgs boson (H +) in TeX decays is presented, where one of the top quarks decays via t???H + b, followed by H +??? two jets ( TeX ). The other top quark decays to Wb, where the W boson then decays into a lepton (e/??) and a neutrino. The data were recorded in pp collisions at TeX by the ATLAS detector at the LHC in 2011, and correspond to an integrated luminosity of 4.7 fb???1. With no observation of a signal, 95 % confidence level (CL) upper limits are set on the decay branching ratio of top quarks to charged Higgs bosons varying between 5 % and 1 % for H + masses between 90 GeV and 150 GeV, assuming TeX .I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
