H04.00001: Spin physics at the Electron Ion Collider Invited Speaker: Alexei Prokudin The future Electron Ion Collider (EIC) will play a crucial role in our understanding of the structure of the building blocks of the visible universe, the proton and the neutron. We provide a concise presentation of the state of the art in the study of the polarized and three-dimensional structure of the nucleon, with particular emphasis on Transverse Momentum Distributions and the future studies at the EIC.

H04.00002: Parton Saturation at Electron Ion Collider Invited Speaker: Anna Stasto In this presentation I will discuss the prospects for testing the phenomenon of the gluon saturation at an Electron Ion Collider. First, the basics and concept of the gluon saturation in high density QCD will be reviewed and implications for the experimental detection discussed. I will focus on the experimental signatures in the Deep Inelastic Scattering on protons and on nuclei at small values of Bjorken x. Several signatures will be discussed: inclusive processes, exclusive vector meson production, particle correlations and forward hadron and particle production. [Preview Abstract] |

H04.00003: EIC Detector Requirements and R{\&}D Invited Speaker: Thomas Ullrich The US-based Electron-Ion Collider (EIC) project is rapidly moving towards its approval stage. The EIC's ability to collide high-energy electron beams with high-energy ion beams will provide access to those regions in the nucleon and nuclei where their structure is dominated by gluons. Moreover, polarized beams in the EIC will give unprecedented access to the spatial and spin structure of gluons and sea-quarks in the proton and light nuclei. The EIC will be an unprecedented collider with luminosities 2-3 orders of magnitude higher than that at HERA over a very wide range of center-of-mass energies from 20 up to 100-140 GeV, while accommodating highly polarized (\textasciitilde 70{\%}) electron and nucleon beams. Equally demanding are the requirements for physics detector(s) that will be needed to carry out the compelling EIC physics program: hermetic coverage in tracking, calorimetry and particle ID within a wide pseudorapidity range, substantial angular and momentum acceptance in the hadron-going direction, as well as high quality hadronic calorimetry among others. Unprecedented for a collider detector are the stringent particle ID requirements that will require various technology to cover the entire momentum range at different rapidities. In my talk I will give an overview of the detector requirements and current general-purpose detector concepts, providing a connection between physics requirements, simulations and the ongoing EIC Detector R{\&}D Program.
