An influence functional for ultrasoft QCD
F. Guerin, E. Iancu
A real-time path integral for ultrasoft QCD is formulated. It exhibits a Feynman's influence functional. The statistical properties of the theory and the gauge symmetry are explici…
A generating functional for ultrasoft amplitudes in hot QCD
F. Guerin
The effective amplitudes for gluon momentum p<<gT in hot QCD exhibit damping as a result of collisions. The whole set of n-point amplitudes is shown to be generated from one functi…
Four-point functions in Keldysh basis
F. Guerin
The Keldysh three- and four-point functions are related to analytical continuations of the Imaginary Time amplitudes,in momentum space. The relation provides an interesting interpr…
Towards softer scales in hot QCD
F. Guerin
An effective theory for the soft field modes in hot QCD has been obtained recently by integrating out the field modes of momenta of order T and g T. The mean hard particle distribu…
Retarded-Advanced N-point Green Functions in thermal field theories
F. Guerin
The general relationship between a Retarded-Advanced Green function of the Real Time formalism and analytical continuations of the Imaginary Time Amplitude is obtained via perturba…
