报告简介：
Most Higgs bosons are expected to decay to a pair of b-quarks, with the Standard Model predicting a branching fraction of about 58%. The observation of this decay would establish the role of the Higgs boson in giving mass to quarks. Unfortunately, such an observation is extremely challenging as the Large Hadron Collider (LHC) produces pairs of b-quarks 10 million times more frequently through processes not involving the Higgs boson than actual Higgs bosons. In this talk, I will first present the evidence of such a decay from the ATLAS experiment. Then I will discuss different algorithms to identify highly boosted hadronically decaying Higgs boson and its application in searches for possible new physics phenomena at the ATLAS experiment.
报告人简介：
Dr. Chen is currently an associate professor in the Department of Physics and Astronomy at Iowa State University.He received his PhD in physics from the University of Pennsylvania in 2003 working on the CDF experiment at the Fermilab. He then joined the University of Maryland as a postdoc and carried out his research on the CP violation at the Stanford Linear Accelerator Center. Since 2009, Dr. Chen has been a faculty at Iowa State University. His current research focus is the ATLAS experiment, one of the two experiments that discovered the Higgs Boson in 2012.
