A Gaussian effective theory for gluon saturation
Edmond Iancu, Kazunori Itakura, Larry McLerran
We construct a Gaussian approximation to the effective theory for the Colour Glass Condensate which describes correctly the gluon distribution both in the low density regime at hig…
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…
Non linear gluon evolution in path-integral form
J. -P. Blaizot, E. Iancu, H. Weigert
We explore and clarify the connections between two different forms of the renormalisation group equations describing the quantum evolution of hadronic structure functions at small…
Comparing different hard-thermal-loop approaches to quark number susceptibilities
J. -P. Blaizot, E. Iancu, A. Rebhan
We compare our previously proposed hard-thermal-loop (HTL) resummed calculation of quark number susceptibilities using a self-consistent two-loop approximation to the quark density…
Froissart Bound from Gluon Saturation
E. Ferreiro, E. Iancu, K. Itakura +1
We demonstrate that the dipole-hadron cross-section computed from the non-linear evolution equation for the Colour Glass Condensate saturates the Froissart bound in the case of a f…
Understanding Geometric Scaling at Small x
E. Iancu, K. Itakura, L. McLerran
Geometric scaling is a novel scaling phenomenon observed in deep inelastic scattering at small x: the total virtual photon-proton cross section depends upon the two kinematical var…
