Query: Can Binary Bound States in a Strongly Coupled Quark-Gluon Plasma be
  observed via dileptons and photons?   Recently there was a significant change of views on physical properties and
underlying dynamics of Quark-Gluon Plasma at $T=170-350 MeV$, produced in heavy
ion collisions at RHIC. Instead of weakly coupled gas of quasiparticles, it is
rather a liquid-like matter with multiple bound states. In this paper we
discuss how one can test these ideas experimentally, using the ``penetrating
probes'' and looking for certain peaks at some invariant masses. In dileptons
the most promising are modified $\rho,\omega$, with $M(T\approx T_c)\sim .5
GeV$ and also near zero binding at $M(T\approx (1.5-2)T_c)=1.5-2 GeV$.
  We also discuss the observability of peaks corresponding to
scalar/pseudoscalar mesons in the two-photon channel.
