    Fate of Heavy Quark Bound States inside Quark-Gluon Plasma

    Xiaojun Yao🇺🇸 · Weiyao Ke🇺🇸 · Yingru Xu🇺🇸 · Steffen Bass🇺🇸 · Thomas Mehen🇺🇸 · Berndt Müller🇺🇸

    Transport equations have been applied successfully to describe the quarkonium evolution inside the quark-gluon plasma, which include both plasma screening effects and recombination. We demonstrate how the quarkonium transport equation is derived from QCD by using the open quantum system framework and effective field theory. Weak coupling and Markovian approximations used in the derivation are justified from a separation of scales. By solving the equations numerically, we study the Upsilon production in heavy ion collisions.

    Multiple charm and hidden charm mesons with strangeness

    Xiu-Lei Ren🇩🇪 · Brenda B. Malabarba🇧🇷 · L. S. Geng🇨🇳 · K. P. Khemchandani🇧🇷 · A. Martinez Torres🇧🇷

    In this talk we summarize our latest results on the study of three-body systems with explicit/hidden charm and with strangeness. In particular, we focus on the and systems, where a charm , isospin and strangeness state is found with a mass around 4140 MeV in the former and a state, with hidden charm, at a mass around 4307 MeV is obtained in the latter. Both states are predictions of our model and the experimental confirmation of them would be important to understand the properties of the strong interaction in the presence of heavy quarks.
