Infrared and light-cone limit in hot QED
E. Petitgirard
In hot gauge theories a breakdown of the hard thermal loop expansion occurs for light-like external momenta or in the infrared region. In QED where a resummation of ladder diagrams…

Breakdown of the Hard Thermal Loop expansion near the light-cone
P. Aurenche, F. Gelis, R. Kobes +1
We discuss the bremsstrahlung production of soft real and virtual photons in a quark-gluon plasma at thermal equilibrium beyond the Hard Thermal Loop (HTL) resummation. The physics…

Retarded/Advanced Correlation Functions and Soft Photon Production in the Hard Loop Approximation
P. Aurenche, T. Becherrawy, E. Petitgirard
We apply the retarded/advanced formalism of real time field theory to the QED or QED like case. We obtain a general expression for the imaginary part of the two-point correlation f…
