The analysis uses data acquired with proton-proton collisions at a center-of-mass energy of 8 TeV and observed with the ATLAS detector at the LHC, corresponding to 20.3 $fb^{-1}$ of integrated luminosity. The search focuses on scalar boson decays into tau lepton pairs, where each decays leptonically ($\tau \rightarrow l \nu_{\tau} \bar{\nu_{l}}$) resulting in one muon, one electron and four neutrinos. No significant excess is observed and upper limits on the signal strength are determined as a function of scalar boson mass.en-USAll Rights Reserved.BottomHiggsTauElectronic Thesis or Dissertation
