19 Open questions  How are the sea quarks and gluons, and their spins, distributed in space and momentum inside the nucleon?  How are these quark and gluon distributions correlated with overall nucleon properties, such as spin direction?  What is the role of the orbital motion of sea quarks and gluons in building the nucleon spin?  Where does the saturation of gluon densities set in?  Is there a simple boundary that separates this region from that of more dilute quark-gluon matter?  If so, how do the distributions of quarks and gluons change as one crosses the boundary?  Does this saturation produce matter of universal properties in the nucleon and all nuclei viewed at nearly the speed of light?  How does the nuclear environment affect the distribution of quarks and gluons and their interactions in nuclei?  How does the transverse spatial distribution of gluons compare to that in the nucleon?  How does nuclear matter respond to a fast moving color charge passing through it?  Is this response different for light and heavy quarks? An EIC is needed! 2016-7-719e-Forum on High-Energy Nuclear Physics in China

20 An EIC is the ultimate machine to provide answers to these questions for the following reasons: 1.A collider is needed to provide kinematic reach well into the gluon-dominated regime; 2.Electron beams are needed to bring to bear the unmatched precision of the electromagnetic interaction as a probe; 3.Polarized nucleon beams are needed to determine the correlations of sea quark and gluon distributions with the nucleon spin; 4.Heavy ion beams are needed to provide precocious access to the regime of saturated gluon densities and offer a precise dial in the study of propagation- length for color charges in nuclear matter. Why EIC? The EIC design exceeds the capabilities of HERA, the only electron-proton collider to date, by adding a)polarized proton and light-ion beams; b)a wide variety of heavy-ion beams; c)2~3 orders of magnitude increase in luminosity to facilitate tomographic imaging; d)wide energy variability to enhance the sensitivity to gluon distributions. 2014/4/2020 2014 高能物理年会， 4.19-23 ，武汉

30 Physics Deliverables of the Stage I EIC 1.Proton spin: Within just a few months of operation, the EIC would be able to deliver decisive measurements, which no other facility in the world could achieve, on how much the intrinsic spin of quarks and gluons contribute to the proton spin as shown in Fig. 1.2 (Right). 2.The motion of quarks and gluons in the proton: Semi-inclusive measurements with polarized beams would enable us to selectively probe with precision the correlation between the spin of a fast moving proton and the conned transverse motion of both quarks and gluons within. Images in momentum space as shown in Fig. 1.3 are simply unattainable without the polarized electron and proton beams of the proposed EIC. 3.The tomographic images of the proton: By measuring exclusive processes, the EIC, with its unprecedented luminosity and detector coverage, would create detailed images of the proton gluonic matter distribution, as shown in Fig. 1.4, as well as images of sea quarks. Such measurements would reveal aspects of proton structure that are intimately connected with QCD dynamics at large distances. 4.QCD matter at an extreme gluon density: By measuring the diffractive cross-sections together with the total DIS cross-sections in electron+proton and electron+nucleus collisions as shown in Fig. 1.6, the EIC would provide the first unambiguous evidence for the novel QCD matter of saturated gluons. The EIC is poised to explore with precision the new field of the collective dynamics of saturated gluons at high energies. 5.Quark hadronization: By measuring pion and D0 meson production in both electron+proton and electron+nucleus collisions, the EIC would provide the first measurement of the quark mass dependence of the hadronization along with the response of nuclear matter to a fast moving quark. 2014/4/2030 2014 高能物理年会， 4.19-23 ，武汉
