138 Chapter 6: Heavy Quark Photon Production Radiation photons emitted from a jet that underwent a smooth, exponential slowdown will differ greatly from one that suffered the emission of a few hard gluons will differ from one that experienced a large number of soft scatterings. Nascent data of γ -hadron correlations from p + p collisions additionally motivates the theoretical exploration of photon bremsstrahlung in heavy ion collisions [442]. In this paper we calculate as a warmup problem, and ultimately as an inter- esting problem in its own right, the 0 th order in opacity energy loss of a heavy quark jet, the radiation associated with the production of a hard parton. We will generalize the problem of a zero mass quark emitting a zero mass photon to a massive quark emitting a massive photon. The lack of theoretical con- sistency in the understanding of light and heavy flavor jet suppression makes massive quark calculations of especial interest [152, 374, 440]; moreover heavy quark predictions from pQCD will be necessary for comparison to AdS/CFT heavy quark drag results [441]. For the case of 0 th order emission QCD and QED are identical but for the replacement of α$_{EM}$ with α$_{s}$ and a color Casimir. Using a massive photon will allow a comparison to already published results on the QCD Ter-Mikayelian effect [305], whose main results were: (1) the Ter- Mikayelian effect leads to a large reduction in 0 th order energy loss ( ∼ 30% for charm quarks), (2) the full 1-loop HTL gluon propagator can be well approx- imated by using a fixed gluon mass m$_{g}$ = m$_{∞}$ = µ/ √ 2, and (3) the small- x , soft gluon, number distribution for 0 th order in opacity is dN (0) pQCD d $^{3}$k = Q $^{2}$α π $^{2}$ω k 2 [ k 2 + m 2 γ + x $^{2}$M 2 $_{Q}$] $_{2}$, (6.1)
