Query: Aspects of quarkonium propagation in a thermal medium as seen by string
  models   We use gauge/string duality to model a heavy quark-antiquark pair in a color
singlet moving through a thermal plasma. In particular, we explore the effect
of velocity on the string tension and Debye screening mass. Then we apply the
results to the analysis of heavy quarkonium bound states. With some
assumptions, we estimate the characteristic size of quarkonium and its
dissociation temperature.
