  2. High Density of Gluons • High number of gluons populates the transverse extend of the proton or nucleus, leading to a very dense saturated wave function:

  3. Gluon Saturation At very high energy parton recombination becomes important. Partons not only split into more partons, but also recombine. Recombination reduces the number of partons in the wave function. I. Balitsky’96 (effective Lagrangian) Yu. K. ’99 (large NcQCD) JIMWLK ‘98-’01 (beyond large-Nc) Number of parton pairs ~ N2

  4. EIC Kinematic Reach EIC would have an unprecedented kinematic reach for nuclear structure functions:it must find something new, something beyond the standard DGLAP approach.

  5. Diffractive over total cross sections • Here’s an EIC measurement which may distinguish saturation from non-saturation approaches. Is this the “smoking gun”? Saturation = Kowalski et al ‘08, plots generated by Marquet Shadowing = Leading Twist Shadowing (LTS), Frankfurt, Guzey, Strikman ‘04, plots by Guzey
