21. In-medium heavy quark potential from lattice QCD and the generalized Gauss-law

Dr Alexander Rothkopf (University of Stavanger)

25/06/2019, 16:40

Oral talk

In this talk I report on recent progress in the determination of the complex heavy quark potential from lattice QCD simulations [1] and show how its temperature dependence can be captured in an analytic parametrization based on an improved generalized Gauss law model [2]. Prospects for in-medium quarkonium phenomenology are discussed. [1] P. Petreczky, A.R., J.Weber, NPA982 (2019) 735 and...

28. Real-Time-Evolution of Heavy-Quarkonium Bound States

Mr Alexander Lehmann (Heidelberg University and University of Stavanger)

25/06/2019, 17:05

Oral talk

Elucidating the production process of heavy quark bound states is a central goal in heavy-ion collisions [1]. Two central questions exist: Do bound states of heavy quarks form in the early time evolution of the glasma? If so, in which time regime can that happen? An answer requires the development of a non-perturbative treatment of the real-time-dynamics of heavy quarkonia. To answer those...

32. Quantum dissipation of quarkonium in quark-gluon plasma: Lindblad equation approach

Mr Takahiro Miura (Osaka University)

25/06/2019, 17:30

Oral talk

In heavy ion collision experiments, quark-gluon plasma (QGP) is expected to be produced and its physical properties have been discussed. Survival probability of a quarkonium is sensitive to the Debye screening of color charges in QGP. The dynamics of quarkonia can be described by master equation for the density matrix in the open quantum system approach. In this approach, the effect of quantum...
