  The intensive synchrotron radiation resulting from quarks interacting with
the collective confining color field in relativistic heavy ion collisions is
discussed. The spectrum of photons with large transverse momentum is calculated
and compared with the experimental data to demonstrate the feasibility of this
type of radiation. A study of the earlier predicted azimuthal anisotropy in the
angular distribution of dileptons with respect to the three-momentum of the
pair is performed as well. This boundary-induced mechanism of lepton pair
production is shown to possess the features that are distinctly different from
the standard mechanisms and can potentially provide an efficient probe of
quark-gluon plasma formation.
