After the discovery of the Standard Model (SM) Higgs boson in 2012, one of the most important tasks for the Higgs sector is to find out all the other decay channels predicted by the SM. Any deviation from the SM prediction is a sign of new physics. In this seminar, searches for Higgs to bb and Higgs to μμ final states are presented using data corresponding to an integrated luminosity of 36.1 fb-1 collected with the ATLAS detector in proton-proton collisions at sqrt(s)=13 TeV at the Large Hadron Collider.
Prof. Haifeng Li is an experimental particle physicist working on the ATLAS experiment at the Large Hadron Collider. He obtained his Ph.D from Shandong University in 2012 with a joint program between Shandong University and University of Wisconsin-Madison. After that, he spent five years working in State University of New York at Stony Brook as a postdoc. In September of 2017, he joined the ATLAS group at Shandong University as a faculty. Prof. Li’s research interests are SM Higgs physics and Beyond SM physics. Currently he is leading a team in ATLAS to search for Higgs to μμ.
