Description

I discuss new results on the extraction of the heavy quark anti-quark potential at non-zero temperature from lattice QCD. Calculations have been performed using Highly Improved Staggered Quark action on lattices with temporal extent Nt=6, 8 and 12. The potential is extracted from the temporal Wilson loops, largely extending the first preliminary calculations using Nt=6 lattices [1]. Implications of the findings for the quarkonium spectral function will be discussed. [1] A. Bazavov and P. Petreczky, Nucl. Phys. A904-905 (2013) 599c
