This thesis re-examines soft dilepton emission from a weakly coupled Quark-Gluon Plasma. It shows that Braaten, Pisarski, and Yuan's result, that the dilepton rate rises as 1/q40 (and the spectral weight scales as 1/q0) at small energy q0 ≪ gT is correct, but that the coefficient they found for this behavior is not correct, because their analysis was incomplete. At still smaller scales, the behavior moderates to ∝ 1/q20 for q0 ≲ g4T, consistent with a finite electrical conductivity. An evaluation of the spectral weight in the q0 ~ g4 T region by kinetic theory techniques is carried out. The spectral weight is then shown to satisfy a sum rule, which makes the determination of electrical conductivity from the Euclidean correlation function very challenging.
