  We propose a particle production mechanism analogous to the particle
photoproduction processes, arising from the gluon-nucleon interactions in
relativistic heavy ion collisions. The comparison is made on the effect of the
gluon-nucleon interactions on the photon production in Au+Au collisions at
$\sqrt{s_{NN}}=$200 GeV and Pb+Pb collisions at $\sqrt{s_{NN}}=$2.76 TeV. The
numerical results indicate that as the collision energy increases, the
contribution of gluon-nucleon interactions becomes more prominent.
