DESCRIPTION:Speakers: Nadia Barnard (University of Cape Town)\nIn a revolu
 tionary paper\, Matsui and Satz proposed using the suppression of quarkoni
 a as a smoking gun signature of deconfinement in relativistic heavy ion co
 llisions. The stunning success of using strong-coupling\, AdS/CFT techniqu
 es to predict the viscosity to entropy density ratio extracted from RHIC a
 nd LHC heavy ion collision data using sophisticated 3+1D relativistic visc
 ous hydrodynamics has prompted further investigation into the physics of a
  strongly-coupled plasma. We compute\, for the first time\, the suppressio
 n of bottomonia in a strongly coupled QGP\, and compare the results to tho
 se from a weakly coupled QGP and to data. The complex binding energies whi
 ch inform the thermal width and hence the $R_{AA}$ of $\\Upsilon$(1S) are 
 determined using imaginary time techniques. Further\, we discuss the valid
 ity of this methodology which solves for strongly coupled binding energies
  using static $q\\bar{q}$ potential models from AdS/CFT by comparing to in
 dependent results.\n\nhttps://indico.tlabs.ac.za/event/75/contributions/11
