Description
The measurement of the Higgs Boson and its cross-section in top associated production allows a
direct measurement of the top quark Yukawa coupling at tree level. This can be compared with the indirect
one in gluon-gluon-fusion production. The decay channel of the ttH system in the multilepton final state
gives one of the largest sensitivities. The considered sub-channel is one with two
same-charged light leptons (electrons or muons) and one hadronically decaying tau-lepton: ttH into 2l+1tau.
This poster gives an overview of the analysis and explains in detail the data-driven background estimation
of the non-reducible background processes. The analysis includes a dataset of 20.3 inverse fb which has
been recorded in LHC Run I at a center-of-mass energy of 8 TeV with the ATLAS detector.
