Query: Mesons versus quasi-normal modes: undercooling and overheating   In holographic models of gauge theories with matter, there generically exists
a first order phase transition in which mesons dissociate. We perform a careful
analysis of the meson and quasi-particle spectra in the overheated resp.
undercooled regimes close to the junction of the two phases. We show that all
overheated finite meson masses eventually become infinitely degenerate, which
implies that any connection to the quasi-particle spectrum is more subtle than
previously suggested. For the Sakai-Sugimoto model no smooth connection between
these spectra is possible.
