Sangyong Jeon

"I am deeply honoured to receive this year’s CAP-TRIUMF Vogt Medal. I would like to thank all my collaborators, students, and postdocs over the years. Without them and the tradition of strong subatomic physics research at McGill, this would not have been possible." winner citation

The Canadian Association of Physicists (CAP) and TRIUMF are pleased to announce that the 2021 CAP-TRIUMF Vogt Medal for Contributions to Subatomic Physics is awarded to Sangyong Jeon, McGill University, in recognition of to recognize his contributions to the theory of relativistic heavy-ion collisions and of the resulting quark-gluon plasma. announcement

Professor Sangyong Jeon’s research is in high-energy nuclear physics and focuses more specifically on the theoretical study of relativistic nuclear collisions. Early on in his career, Professor Jeon has set high standards for all field-theoretical many-body calculations of strongly interacting matter to follow, by estimating the viscosities of a scalar field theory at finite temperatures using diagrammatic techniques. The string of papers outlining that powerful approach has had impact on many different fields and has influenced nuclear science, particle physics, fundamental field theory studies, and theoretical cosmology, to name a few.

In addition to his work on fundamental theory, Sangyong Jeon has been responsible for several of the phenomenology cornerstones of contemporary high-energy nuclear physics. For instance, he has spearheaded the development of relativistic fluid dynamics and of relativistic kinetic theory as applied to high energy heavy-ion collisions, such as those performed at the Relativistic Heavy-Ion Collider (RHIC, at Brookhaven National Laboratory) and at the Large Hadron Collider (LHC, at CERN). His work has enabled the community to make great strides forward in the quantification of the out-of-equilibrium behaviour of Quantum Chromodynamics, the theory of the nuclear strong interaction. nominator citation
