We provide a broad overview of the theoretical status and phenomenological applications Color Glass Condensate effective field theory describing universal properties saturated gluons in hadron wavefunctions that are extracted from deeply inelastic scattering hadron-hadron collision experiments at high energies.
We continue the study of effective action for low x physics based on a Wilson renormalization group approach. express full nonlinear equation in terms average value and fluctuation extra color charge density generated by integrating out gluons with intermediate values $x$. This form clearly exhibits nature phenomena driving evolution should serve as basis analysis saturation effects at high gluon small
We compute the distribution functions for gluons at very small x and not too large values of transverse momenta. extend McLerran-Venugopalan model by using renormalization group methods to integrate out effects due those which generate an effective classical charge density Weizs\"acker-Williams fields. argue that this can be extended from description nuclei hadrons yet smaller x. This generates a Lipatov like enhancement intrinsic gluon function non-trivial momentum dependence as well....
In this paper we derive the complete Wilson renormalization group equation which governs evolution of gluon distribution and other gluonic observables at low x arbitrary density.Received 17 June 1998DOI:https://doi.org/10.1103/PhysRevD.59.014015©1998 American Physical Society
We analyze the general nonlinear evolution equations for multigluon correlators derived in a previous paper by restricting ourselves to double logarithmic region. In this region our equation becomes local transverse momentum space and amenable simple analysis. It provides complete generalization of Gribov-Levin-Ryskin equation. find that full log at high density strikingly different from its linear doubly Dokshitzer-Gribov-Lipatov-Alterelli-Parisi counterpart. An effective mass is induced...

We consider the single-inclusive minijet cross section in pA at forward rapidity within color glass condensate model of high energy collisions. show that nucleus appears black to incident quarks except for very large impact parameters. A markedly flatter p(t) distribution as compared QCD dilute perturbative limit is predicted transverse momenta about saturation scale, which could be Q(2)(s) approximately 10 GeV2 a gold boosted (as BNL-RHIC).
A bstract We calculate the one-loop corrections to single inclusive hadron production in Deep Inelastic Scattering (DIS) at small x forward rapidity region using Color Glass Condensate formalism. show that divergent parts of next leading order (NLO) either cancel among each other or lead (rapidity) evolution (LO) dipole cross section according JIMWLK equation and DGLAP parton-hadron fragmentation function. The remaining finite constitute NLO ( α s ) LO DIS .
We compute the quantum corrections to gluon distribution function in background of a non-Abelian Weizs\"acker-Williams field. These are valid all orders effective coupling ${\mathrm{\ensuremath{\alpha}}}_{\mathit{s}}$\ensuremath{\mu}, where ${\mathrm{\ensuremath{\mu}}}^{2}$ denotes average valence quark color charge squared per unit area. find ln(1/x) logarithmic classical function. The one-loop field do not contribute these singular terms Their effect is cause running...
We calculate production cross sections of a forward quark-gluon pair and two gluons at midrapidity in deep inelastic scattering high energy proton-nucleus collisions. The calculation is performed the framework color glass condensate formalism. first quasiclassical approximation, which includes multiple rescatterings target. then proceed to include effects nonlinear small-$x$ evolution sections. It interesting note that our result for two-gluon section appears be direct violation...

We calculate the photon production cross-section in $pA$ collisions under assumption that nucleus has reached saturation regime, while proton can be described by standard parton distribution functions. show due to strong classical field $O(1/g)$ of nucleus, bremsstrahlung diagrams become dominant over direct diagrams. In particular, we $\gamma-$jet transverse momentum spectrum and correlations are very sensitive gluon effects nucleus.
