Prompt and Non-Prompt J/psi as Probes of the Quark-Gluon Plasma

Measurement of prompt and non-prompt J/psi charmonium in ultra-relativistic Pb-Pb collisions to probe the quark-gluon plasma. Prompt J/psi test dissociation by color screening and regeneration from charm pairs, while non-prompt J/psi from beauty-hadron decays probe heavy-quark energy loss and transport; the components are separated via displaced decay topology and compared with hadronization, transport, and energy-loss models.
