Searches for the Higgs boson decays and are performed using data corresponding to an integrated luminosity of collected with the ATLAS detector in pp collisions at TeV at the LHC. No significant signals are observed, in agreement with the Standard Model expectation. For a Higgs boson mass of 125 GeV, the observed (expected) upper limit at the 95% confidence level on the branching fraction is () and on is (). These results represent improvements by factors of about five and six on the previous best limits on and respectively.
