Abstract：We attempt to deal with the direct photon production phenomena in p+p, d+Au and Au+Au collisions at RHIC energy, √sNN=200 GeV and in Pb+Pb-collisions at LHC energy, √sNN=2.76 TeV on the basis of a non-standard framework outlined in the text. Comparisons of the model-based results with the measured data on some observables reveal fair agreement and they are modestly consistent with the results obtained by some other models of 'Standard' framework.
(Relativistic heavy-ion collisions (collisions induced by light ions studied to calibrate relativistic heavy-ion collisions should be classified under both 25.75.-q and sections 13 or 25 appropriate to the light ions))
