Query: Chiral symmetry breaking and confinement effects on dilepton and photon
  production around $T_c$   Production rates of dileptons and photons from the quark-gluon (QGP) phase
are calculated taking into account effects of confinement and spontaneous
chiral symmetry breaking (\chi SB) not far from the transition temperature
$T_c$. We find that the production rates of dileptons with large momenta and of
photons originating from the QGP around $T_c$ are suppressed by the \chi SB
effect. We also discuss to what extent information about details of the chiral
transition, such as its characteristic temperature range and the steepness of
the crossover, are reflected in these quantities.
