David M. Dennison Collegiate Professor of Physics
About
Professor Qian focuses his current research on the ATLAS experiment at CERN’s Large Hadron Collider (LHC). He led the ATLAS search of the Standard Model Higgs boson in one of its major decay modes and was a leading contributor to its subsequent discovery. His current physics interests include measurements of the properties of the Higgs boson and searches for new physics beyond the Standard Model. For the latter, he is engaged in searches of experimental signatures expected from an extended Higgs sector, the production of dark matter particles as well as new heavy resonances at the LHC. Previously, Professor Qian did his research with the DØ experiment at the Fermilab Tevatron proton-antiproton and with the L3 experiment at CERN’s Large Electron-Positron Collider (LEP). He contributed to the discovery of the top quark at Tevatron and the determination of three light neutrino species at LEP.
