DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HEPTUW/23/">
 The imaginary part of the heavy-quark potential from real-time Yang-Mills 
 dynamics</a>\nby Kirill Boguslavski (TU Wien) as part of HEP seminars TU W
 ien (Vienna)\n\n\nAbstract\nThe suppression of heavy quark-antiquark bound
  states like bottomonium in heavy-ion collisions is an important observabl
 e for the quark-gluon plasma state. Theoretically\, this can be quantified
  by the heavy-quark potential. In this talk\, I will present our results o
 n extracting its imaginary part using classical-statistical simulations of
  real-time Yang-Mills dynamics in classical thermal equilibrium. We compar
 e our results to perturbation theory calculations in hard thermal loop for
 malisms. We find that\, when considered as a function of m_D r\, where m_D
  is the soft scale\, the imaginary part of the heavy-quark potential becom
 es independent of the lattice spacing at sufficiently small r and agrees w
 ell with perturbative results. We finally relate the short-distance behavi
 or of the potential to the heavy-quark transport coefficient κ\, providin
 g an estimate of the latter.\n
