Description

After the discovery of the Higgs boson in 2012, ATLAS experiment at LHC is performing precise measurements to reveal the nature of vacuum. We discuss the first observation of the Higgs boson decaying into bb-bar pair and tt-barH production. These measurements indicate the Yukawa coupling between the Higgs boson and the third generation quark is consistent with the expectation of the Standard Model. Also, the stability of vacuum based on the latest mass measurement of top quark and W± boson is discussed. (author)
