Static quark-antiquark pairs at finite temperature — Nora Brambilla¹, •Jacopo Ghiglieri¹, Peter Petreczky², and Antonio Vairo¹ — ¹Technische Universität München, Physics Department T30f, James-Frank-Str. 1, 85747 Garching, Germany — ²RIKEN-BNL Research Center & Physics Department Brookhaven National Laboratory, Upton, NY 11973, USA

In a framework that makes close contact with modern effective field theories for non-relativistic bound states at zero temperature, we study the real-time evolution of a static quark-antiquark pair in a medium of gluons and light quarks at finite temperature, obtaining the potential and decay widths in different temperature regions, with new results in the 1/r >> T regime.
