Description
Perturbative evolution of QCD cross sections is governed by the DGLAP evolution of parton distribution and fragmentation functions. This formalism breaks down at small Bjorken x (high energy) due to high gluon
density (gluon saturation) effects. The Color Glass Condensate (CGC)
formalism is an effective action approach to QCD at
small Bjorken x which includes gluon saturation. The CGC
formalism nevertheless breaks down at intermediate/large Bjorken x. Here we describe the first steps taken towards the
derivation of a new approach, with the ultimate goal of having a
unified formalism for calculation of QCD cross sections at both large and small Bjorken x. Application of the new approach to calculation of observables in EIC will be discussed.
