Abstract
H->bb is the most dominant decay of the Higgs boson in the Standard Model. However, ATLAS and CMS experiment did not observe any evidence in Run1, because of large amount of backgrounds and limited data statistics. Therefore, the search is followed with great attention in Run2. In this seminar, I will present an evidence for the H->bb decay with the ATLAS detector, particularly focusing on Z->ll associated production channel, and b-jet energy corrections to improve the Higgs mass resolution. I will also present level-1 endcap muon trigger work at the beginning of Run2.
