Therefore 

Hence the distribution of emitted photons is

This does not agree with [305], but does agree with the—presumably cor- rected version—in [447]. Note that we have not included radiation into the longitudinal mode. 

## E.2.5 Classical Calculation, Massive Quark Jet and Massive Photon 

Note that while the sum over polarizations changes to $^{∑}$$_{λ}$ϵ$_{µ}$ ϵ ∗ ν = − g$_{µν}$ + k$_{µ}$k$_{ν}$/m 2 $_{g}$, Eq. (E.28) is unchanged; the additional terms exactly cancel each other. We need to calculate the relevant dot products using the four momenta
