Wee partons in large nuclei: from virtual dream to hard reality
We construct a weak coupling, many body theory to compute parton
distributions in large nuclei for . The wee partons are highly
coherent, non--Abelian Weizs\"{a}cker--Williams fields. Radiative corrections
to the classical results are discussed. The parton distributions for a single
nucleus provide the initial conditions for the dynamical evolution of matter
formed in ultrarelativistic nuclear collisions.Comment: Plenary talk at Quark Matter '95, Monterey, CA, Jan 1995; LaTex file

Hadronic scattering in the Color Glass Condensate
Multi-particle production in QCD is dominated by higher twist contributions.
The operator product expansion is not very effective here because the number of
relevant operators grow rapidly with increasing twist. The Color Glass
Condensate (CGC) provides a framework in QCD to systematically discuss
"classical" (multiple scattering) and "quantum" evolution (shadowing) effects
in multi-particle production. The apparently insuperable problem of
nucleus-nucleus scattering in QCD simplifies greatly in the CGC. A few examples
are discussed with emphasis on open problems.Comment: 7 pages, Plenary talk at XXth Blois Conference, clarifying remark

From many body wee parton dynamics to perfect fluid: a standard model for heavy ion collisions
We discuss a standard model of heavy ion collisions that has emerged both
from the experimental results of the RHIC program and associated theoretical
developments. We comment briefly on the impact of early results of the LHC
program on this picture. We consider how this standard model of heavy ion
collisions could be solidified or falsified in future experiments at RHIC, the
LHC and a future Electron-Ion Collider.Comment: Extended version of Plenary Talk at the 35th International Conference

Parton saturation, production, and equilibration in high energy nuclear collisions
Deeply inelastic scattering of electrons off nuclei can determine whether
parton distributions saturate at HERA energies. If so, this phenomenon will
also tell us a great deal about how particles are produced, and whether they
equilibrate, in high energy nuclear collisions.Comment: LaTex 6 pgs., invited talk at XXXIVth Rencontres de Moriond, march
