"Quarkonium production in heavy ion collisions: open quantum system, effective field theory and transport equations"

Presented by Xiaojun Yao, Duke University

Thursday, January 24, 2019, 12:00 pm — Building 510, Room 1-224

In this talk, I will present a connection between two approaches of studying quarkonium dynamics inside quark-gluon plasma: the open quantum system formalism and the transport equation. I will discuss insights from the perspective of quantum information. I will show that under the weak coupling and Markovian approximations, the Lindblad equation turns to a Boltzmann transport equation after a Wigner transform is applied to the system density matrix. I will demonstrate how the separation of physical scales justifies the approximations, by using effective field theory of QCD. Finally, I will show some phenomenological results based on the derived transport equation.
