Thermodynamics of open and hidden charmed mesons within the NJL model
Description
We consider effects of temperature on the masses of mesons containing charmed quarks, by considering the SUf(3) Nambu-Jona-Lasinio model after formally replacing ms by mc. In the temperature range of interest, we find no Mott-like transition of the J/Ψ state into the Danti D continuum, indicating that within this model, it is not the mechanism whereby J/Ψ suppression occurs.
