An infrared singularity in the damping rate for longitudinal gluons in hot QCD
We determine the singularity in $\gamma_l(0)$, the longitudinal damping rate for on-shell gluons with zero momentum in hot QCD. This result shows in particular that $\gamma_l(0)$ is different from $\gamma_t(0)$, the corresponding damping rate for transverse gluons which is known to be finite. The fa...
