In medium dynamics of heavy particles

Abstract

The hierarchy of scales of heavy quarks and their bound states in a quark gluon plasma makes the system ideally suited for the use of effective field theories and the formalism of open quantum systems. We utilize these tools to perform a first principles treatment of these heavy particles in medium and analyze the regimes in which the dynamics take the form of a Langevin equation in which the medium and the heavy particle interact via random "kicks" altering the particle's momentum.
