The proposed workshop is dedicated to studying small-x physics in the beyond the eikonal approximation, that is, concentrating on the phenomena suppressed by one or more powers of Bjorken x which are usually neglected in the traditional eikonal small-x physics. These include questions about the proton spin structure and the spin puzzle at small x, involving the spin-dependent PDFs and TMDs, along with the power-of-x corrections to the eikonal scattering on a nucleus, which are enhanced by the powers of the atomic number of a large nucleus and are, therefore, important. All these questions are central to the physics to be probed at the future Electron-Ion Collider (EIC). Attempts at unifying large-x and small-x evolution will also be discussed.
