    • Charmonium moving through a strongly coupled QCD plasma: A holographic perspective 

      Hohler, Paul M.; Yin, Yi (American Physical Society, 2013-10)
      The properties of charmonium in a strongly coupled QCD-like plasma at finite momentum are studied. This is based upon a “bottom-up” holographic model which has been previously shown to reproduce charmonium phenomenology ...

      Stephanov, M. A.; Yin, Y. (American Physical Society, 2012-10)
