ABOUT ME

I'm currently a student at University of Science and Technology of China (USTC) pursuing a PH.D. in high energy physics.
I'm studying relativistic heavy ion collisions in the ATLAS experiment at the Large Hadron Collider at the CERN laboratory. My research is dedicated to quarkonia production and muon efficiency.

Heavy Ion Collisions
--The little bang

More than 99% of the normal matter we see exists in protons and neutrons (nucleons). Nucleons are further composed of quarks and gluons, whose interactions are described by the Quantum Chromo Dynamics theory (QCD). Under normal conditions, quarks are confined inside the nucleons. At extremely high temperature and density, matter turns into the so called Quark-gluon plasma (QGP) phase where quarks become deconfined. This phase is believed to have existed during the first 10 microseconds after the universe was born in the Big Bang.
Experimentally, QGP can be created by colliding two large nuclei at very high energy. The resulting hot and dense fireball is expected to expand under its own pressure, and cool down. Various properties of the QGP such as temperature, pressure, chemical potential, transport coefficient can be deduced from thousands of final state particles emitted from the fireball and detected with large scale particle detectors surrounding the interaction region.
