“…We now turn to the LHeC in its heavy-ion mode [26], which would scatter electrons with E e = 60 GeV on a beam of nuclei from the LHC, with E A = 2.75 TeV per nucleon resulting in √ s = 812 GeV per nucleon. The corresponding integrated luminosity could reach 10 fb −1 , being 10 times bigger than the full integrated luminosity achieved in ep collisions at DESY-HERA.…”

“…Now we analyze the higher-energy upgrade of the LHeC (HE-LHeC) [26,27]. The High-Energy Large Hadron Collider (HE-LHC) is a future energy upgrade of the LHC and its heavy-ion mode considers a beam of nuclei with E A 4.9 TeV per nucleon resulting in √ s 1.1 TeV per nucleon.…”

“…Finally, we discuss eA collisions at the FCC-eA [26,27] machine that would be performed with a lead beam with energy per nucleon of E A = 19.7 TeV, which would give √ s 2.2 TeV per nucleon with expected luminosity is L = 54 × 10 32 cm −2 s −1 . This is in the context of a Future Circular Collider-hadron-hadron mode (FCC-hh) that would provide pp collisions with √ s = 100 TeV.…”

We study the diffractive jet production in electron-ion collisions in the kinematic region where the mass M X of the diffractive final state is larger than Q 2. Based on parton saturation framework, predictions are done for the kinematics of future or possible eA machines as the EIC, LHeC, HE-LHeC, and FCC-eA. We analyze the differential cross section as a function of jet (gluon) transverse momentum and from the experimental point of view this observable could be used to extract the saturation scale as a function of x IP .

“…It will also provide a kinematically well defined reference to quantify cold nuclear matter effects. For completeness it is noted that a similar accelerator proposal (LHeC) with complementary kinematic coverage and physics programe is being evaluated by the European Strategy for Particle Physics [9,10]. The EIC is considered a key component for the future nuclear physics program in the US and as such is among the key recommendations of the Nuclear Science Advisory Committee (NSAC) Long Range Plan from 2015.…”

Quarks and gluons are the fundamental constituents of nucleons. Their interactions rather than their mass, is responsible for 99% of the mass of all visible matter in the universe. Measuring the fundamental properties of matter has had a large impact on our understanding of the nucleon structure and it has given us decades of research and technological innovation. Despite the large number of discoveries made, many fundamental questions remain open and in need of a new and more precise generation of measurements. The future Electron Ion Collider (EIC) will be a machine dedicated to hadron structure research. It will study the content of protons and neutrons in a largely unexplored regime in which gluons are expected to dominate and eventually saturate. While the EIC will be the machine of choice to quantify this regime, recent surprising results from the heavy ion community begin to exhibit similar signatures as those expected from a regime dominated by gluons. Many of the heavy ion results that will be discussed in this document highlight the kinematic limitations of hadron-hadron and hadron-nucleus collisions. The reliability of using as a reference proton-proton (pp) and proton-Nucleus(pA) collisions to quantify and disentangle vacuum and Cold Nuclear Matter (CNM) effects from a Quark Gluon Plasma (QGP) may be under question. An selection of relevant pp and pA results which highlight the need of an EIC will be presented.

“…The Large Hadron-electron Collider (LHeC) [1][2][3], planned at the LHC, may complement the proton ring with an electron beam, allowing to perform deep inelastic scattering (DIS) with electrons and protons at TeV energies. Its electron beam energy may be chosen to be 60 or 50 GeV.…”

At the proposed electron-proton collider LHeC electroweak interactions can be uniquely studied in a largely unexplored kinematic region of spacelike momentum transfer. We simulate inclusive neutral- and charged-current deep-inelastic lepton proton scattering cross section data at center-of-mass energies of 1.2 and 1.3 TeV, and estimate the uncertainties of Standard Model parameters as well as of parameters describing physics beyond the Standard Model. A precision at sub-percent level is expected for the measurement of the weak neutral-current couplings of the light-quarks to the Z boson, $$g_{A/V}^{u/d}$$ g A / V u / d , improving their present precision by more than an order of magnitude. The weak mixing angle can be determined with a precision of about $$\Delta \sin ^2\theta _\text {W}=\pm \,0.00015$$ Δ sin 2 θ W = ± 0.00015 , and its scale dependence can be studied in the range between about 25 and 700 GeV. An indirect determination of the W-boson mass in the on-shell scheme is possible with an experimental uncertainty down to $$\Delta m_{W}=\pm \,6\,\text {MeV}$$ Δ m W = ± 6 MeV . We discuss how measurements in deep-inelastic scattering compare with those in the timelike domain, and which aspects are unique, for instance electroweak parameters in charged-current interactions. We conclude that the LHeC will determine electroweak physics parameters, in the spacelike region, with unprecedented precision leading to thorough tests of the Standard Model and possibly beyond.
