Today I read a paper titled “Wee partons in large nuclei: from virtual dream to hard reality”
The abstract is:
We construct a weak coupling, many body theory to compute parton distributions in large nuclei for $x\ll A^{-1/3}$.
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.
