A Gaussian effective theory for gluon saturation
TLDR
In this article, a Gaussian approximation to the effective theory for the color glass condensate was constructed, which describes correctly the gluon distribution both in the low density regime at high transverse momenta (above the saturation scale Q s ), and in the high density regime below Q s, and provides a simple interpolation between these two regimes.About:

The Color glass condensate and high-energy scattering in QCD
Edmond Iancu,Raju Venugopalan +1 more
TL;DR: The Color Glass Condensate (CGC) as mentioned in this paper was proposed to describe the behavior of the small x components of the hadronic wave function in QCD, and the Green functions of the theory satisfy Wilsonian renormalization group equations which reduce to standard linear QCD evolution equations in the limit of low parton densities.

Saturation and BFKL dynamics in the HERA data at small-x
TL;DR: In this paper, the HERA data for the inclusive structure function F2(x,Q2) for x ⩽10−2 and 0.045⩽Q2⩻45 −GeV2 can be well described within the color dipole picture, with a simple analytic expression for the dipole-proton scattering amplitude, which is an approximate solution to the nonlinear evolution equations in QCD.

Renormalization group evolution of multi-gluon correlators in high energy QCD

TL;DR: In this article, the authors evaluate the functional Langevin equation that describes the Balitsky-JIMWLK hierarchy of renormalization group equations for the x evolution of multi-point Wilson line correlators and compare the results to mean-field Gaussian and large Nc approximations.

Asymptotic Freedom in Parton Language
Guido Altarelli,Giorgio Parisi +1 more
TL;DR: In this article, the main body of predictions of the theory for deep-inleastic scattering on either unpolarized or polarized targets is re-obtained by a method which only makes use of the simplest tree diagrams and is entirely phrased in parton language with no reference to the conventional operator formalism.
Journal ArticleDOI
Semihard processes in QCD
TL;DR: In this article, the effects of parton-parton interactions (screenings), that stop the increase of the cross sections near their unitarity limit, and the coherent emission of soft gluons by the global colour charge of whole groups of harder particles, are studied in detail.

Computing quark and gluon distribution functions for very large nuclei.
Larry McLerran,Raju Venugopalan +1 more
TL;DR: It is argued that the distribution functions for quarks and gluons are computable at small {ital x} for sufficiently large nuclei, perhaps larger than can be physically realized, and that weak coupling methods may be used.

Operator expansion for high-energy scattering
Ian Balitsky,Ian Balitsky +1 more
TL;DR: In this article, the leading logarithms for high-energy scattering can be obtained as a result of evolution of the non-local operators (straight-line ordered gauge factors) with respect to the slope of the straight line.

Small-x F 2 structure function of a nucleus including multiple Pomeron exchanges
TL;DR: In this paper, the authors derived an equation determining the small-x evolution of the F{sub 2} structure function of a large nucleus which includes all multiple Pomeron exchanges in the leading logarithmic approximation using Mueller{close_quote}s dipole model.
