Description
Our understanding of the structure of nucleons is described by the properties and dynamics of quarks and gluons in  the theory of quantum chromodynamics. With advancements in theory and the development of phenomenological tools we are preparing for the next step in subnuclear tomographic imaging at a future electron-ion collider. High center-of-mass energies (√ s ≈ 45 - 150 GeV) in combination with extremely high luminosities (1033-44cm-2s-1) will provide the precision and a kinematic reach well into the gluon dominated regime of very low parton momenta where a saturation of the gluon density is expected, in particular in collisions of electrons wiht heavy nuclei. In addition, highly polarized nucleon and electron beams (Pbeam ≈70%) can probe the parton polarizations in previously unexplored kinematic regions and unprecedented accuracy, as well as address the role of orbital angular momentum with respect to the nucleon spin. This talk will summarize the theoretical and technical challenges of such a versatile experimental endeavour as planned with the eRHIC facility at Brookhaven National Laboratory.
