3. S H Lee 3 J/  in Quark-gluon plasma Matsui and Satz: J/  will dissolve at Tc due to color screening Lattice MEM : Asakawa, Hatsuda, Karsch, Petreczky …. J/  will survive Tc and dissolve at 2 Tc Potential models (Wong …) : Consistent with MEM Wong. Refined Potential models with lattice (Mocsy, Petreczky…) : J/  will dissolve slightly above Tc Lattice after zero mode subtraction (WHOT-QCD) : J/  wave function hardly changes at 2.3 Tc AdS/QCD (Kim, Lee, Fukushima..) : J/  mass change And so on ……….
