Jet tomography of hot and cold nuclear matter

Theoretical Physics Colloquium by Prof. Xin-Nian Wang.
This presentation was held live on July 22, 2020 as part of the theoretical physics colloquium series hosted by Prof. Igor Shovkovy at the Arizona State University. The series features high-quality interactive presentations on current advances in theoretical physics by active researchers in the field of theoretical physics.
Abstract for this presentation:
When an energetic parton propagates through hot or cold nuclear matter, it will interact with the constituents of the matter. The energy loss and momentum broadening it experiences along its propagation path is the subject of intense experimental and theoretical studies. Within pQCD, what we have learned about this has enabled us to use fast partons or jets as a tomographic tool to glean properties and the hot and dense matter from experimental data of heavy-ion and electron-ion collisions. I will give a brief review on theoretical and phenomenological studies of jet tomography and discuss what we have and will learn about properties of hot and cold nuclear matter.
