Research Interest: Particle physics experiments

Prof. Yang received B.S. from University of Science and Technology of China in 2005, and obtained the PhD of Physics from California Institute of Technology in 2012. He held postdoc positions at Caltech from Jan-Mar 2013 and at University of Zurich from Apr 2013 to Jan 2016. He joined the department of physics and astronomy at SJTU in Feb 2016.

Yang is interested in the most fundamental questions about the nature of our Universe: its fundamental building blocks and the way they interact. As a member of the Compact Muon Solenoid (CMS) Collaboration at the Large Hadron Collider (LHC) at CERN, in Geneva, Switzerland, Yang performed precise intercalibration for the CMS crystal electromagnetic calorimeter (ECAL) [1] and co-discovered the Higgs boson[2-3], a particle that gives masses to fundamental particles in the Standard Model (SM) of particle physics, which is a quite successful model but only explains about 5% of the energy-mass content of the Universe. The other 27% is made of mysterious substance known as dark matter, the rest is dark energy. Yang searched for dark matter particles that might be produced in high energy collisions at the LHC [4].

Yang is now working on the PandaX experiments located in China Jinping Underground Laboratory (CJPL) in Xichang, Sichuan, and the ATLAS experiment at the LHC. PandaX is a series of experiments that search for signals that come from dark matter particles interacting with Xenon atoms, and search for signals that come from neutrinoless double beta decays of Xe-136 isotope.  

Yang received “CMS Achievement awards” in 2011 due to contributions to the CMS ECAL intercalibration with neutral pions and etas.
