Query: Holographic Meson Melting   The plasma phase at high temperatures of a strongly coupled gauge theory can
be holographically modelled by an AdS black hole. Matter in the fundamental
representation and in the quenched approximation is introduced through
embedding D7-branes in the AdS-Schwarzschild background. Low spin mesons
correspond to the fluctuations of the D7-brane world volume. As is well known
by now, there are two different kinds of embeddings, either reaching down to
the black hole horizon or staying outside of it. In the latter case the
fluctuations of the D7-brane world volume represent stable low spin mesons. In
the plasma phase we do not expect mesons to be stable but to melt at
sufficiently high temperature. We model the late stages of this meson melting
by the quasinormal modes of D7-brane fluctuations for the embeddings that do
reach down to the horizon. The inverse of the imaginary part of the quasinormal
frequency gives the typical relaxation time back to equilibrium of the meson
perturbation in the hot plasma. We briefly comment on the possible application
of our model to quarkonium suppression.
