In the exact propagator for finite temperature gluons the location of the transverse and longitudinal poles in the gluon propagator are unknown functions of wave vector: ωT (k) and ωL(k). The residues of the poles, also unknown, fix the normalization of the one gluon vector potential and thus of the field strength. The naive energy density ~ E · ~ D + ~ B · ~ H is not correct because of dispers...
