An influence functional for ultrasoft QCD
arXiv:hep-ph/0212036 · doi:10.1142/9789812704498_0053
Abstract
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 explicit. The correspondence is established with the alternative version, where a noise term enters a transport equation.
