  Instanton effects may have implications for hadronization of quark-gluon
plasma as it cools. Here we study dispersion relations of mesons in a strongly
coupled plasma with an instanton background present. It will be shown that at
higher energies the instanton effect diminishes and some comments on the
limiting velocity of mesons in the plasma. the profile function of mesons on
the gravity side is considered also because of its relevance to energy loss of
quark in plasma.
