In the past years, the Large Hadron Collider (LHC) at CERN has been focusing on the direct searches of new physics and resulted in the discovery of the Higgs boson (Nobel Prize in 2013). With the new data collected during 2015-2016 on the 13 TeV high energy frontier, a great number of direct new physics searches have been carried out. However, no new excitement appears. As the energy scale (13 TeV) is not going to be increased as currently planned, the LHC is now in a transition period starts to shift its focus gradually from direct searches of new physics to precision measurements of the SM properties for the indirect searches of new physics. 

This seminar will give a brief introduction of the direct and indirect searches of new physics at hadron colliders, using the heavy diboson resonance searches (direct search) and the W boson mass precision measurements (indirect search) as examples.  

Dr. Hengne Li    Senior Research Scientist at University of Virginia, Dr. Li has 13 years of experiences in High Energy Physics, participated in several major experiments in the field, such as ILC/ILD/CALICE, D0, CMS, and ATLAS, with experiences covering physics analysis, detector R&D, detector simulation, data reconstruction, and grid/cloud computing. Dr. Li has worked as the D0 W mass analysis convener and the CMS Level-2 coordinator for physics validation and MC production. Dr. Li has more than 400 collaboration signature publications including 15 first author/main contributor publications.
