After the Higgs boson discovery in July 2012, a precise measurement of its properties is critical to verify the Standard Model. The top quark presents the largest Yukawa coupling among the SM fermions and measuring its value is a probe to new physics beyond the SM. The Higgs associated production with top-quark pair (ttH) provides direct access to the top Yukawa coupling. 
Search for ttH has been performed in ATLAS using 36.1 /fb dataset at 13 TeV centre-of-mass energy. The result constitutes experimental evidence for ttH production !
