Haichen Wang (LBNL) Title: The Higgs boson and the top quark share the stage

February 15, 2018 @ 4:00 pm - 5:00 pm

The top quark plays an important role in the collider phenomenology of the Higgs boson, and the study of the interplay between the top quark and the Higgs boson may provide key insights to some critical questions in particle physics. A milestone in the experimental study of the top-Higgs sector of the Standard Model will be the observation of the Higgs boson production in association with top quarks (ttH), a direct evidence for the top-Higgs Yukawa coupling. With 36.1 fb-1 pp collisions at 13 TeV, the ATLAS experiment performed searches for the ttH production in several channels and found the evidence for this production. In this talk, I start with a brief overview on the experimental understanding of the Higgs boson properties and motivate the study of the top-Higgs Yukawa coupling. I then present the ATLAS ttH searches with a focus on the diphoton channel. In the end, I discuss the prospect of the ttH study and its impact on other aspects of the LHC physics program.
