Nonperturbative potential for study of quarkonia in QGP

Understand

A thermal potential can be defined to facilitate understanding the behavior of quarkonia in quark-gluon plasma.

• A nonperturbative evaluation of this potential from lattice QCD is difficult, as it involves real-time corelation function, and has often involved the use of Bayesian analysis, with its associated systematics.
• In this work we show that using the properties of the static quarkonia thermal correlation functions, one can directly extract a thermal potential for quarkonia from Euclidean Wilson loop data.
• This leads to a controlled extraction, and allows us to judge the suitability of various model potentials.
