Y04.00001: Quark and Gluon Imaging at the EIC Invited Speaker: Daria Sokhan The Electron-Ion Collider (EIC), to be constructed at the site of Brookhaven National Lab within this decade, will be the world’s first to collide polarised electron beams with polarised protons and light ions and unpolarised nuclei up to Uranium. With centre-of-mass energies ranging from 20 to 140 GeV and luminosities of 10$^3$$^3$$^−$$^3$$^4$ cm$^−$$^2$ s $^−$$^1$ , it will open up new, wide realms of phase space, reaching from the valence quark region to deep into the quark-gluon sea, for study with an unprecedented level of precision. This will enable three-dimensional imaging of the quark and gluon structure of the nucleon and nucleus and a mapping of its internal dynamics across the widest span of parton momenta. This talk presents an overview of the imaging programme planned for the EIC and discusses the types of scattering processes which will make it possible. [Preview Abstract] |

Y04.00002: Small-x Physics in the EIC Era Invited Speaker: Matthew Sievert One of the central missions of the coming Electron-Ion Collider (EIC) is to discover evidence of gluon saturation in the nucleon and nuclei in the small-x regime at high energies. This phenomenon indicates the onset of the nonlinear, high-density regime of QCD characterized by intense semi-classical gluon fields, and it is intimately connected with the mechanism of unitarization in QCD itself. In recent years, significant progress has been made in refining the theoretical framework of small-x physics and gluon saturation, including the calculation of observables to NLO accuracy, the generalization to spin-dependent parton distributions at small x, and understanding of the relationship between the small-x and TMD formalisms. In this talk I will review recent developments with an emphasis on observables in the coming EIC era. [Preview Abstract] |

Y04.00003: Lattice QCD in the EIC Era Invited Speaker: William Detmold In this talk, I will discuss the current status of lattice QCD calculations relevant to the EIC science program as well as expectations for calculations in the lead-up to EIC data taking. In particular I will focus upon the areas of partonic physics in nucleons and nuclei and on the origin of the mass of the proton. [Preview Abstract] |
