The Large Hadron-electron Collider (LHeC) is a proposed upgrade of the LHC at CERN. An Energy Recovery Linac in racetrack configuration will provide 60 GeV electrons to collide with the HL-LHC ion beams and, eventually, with those from the HE-LHC and the FCC-hh. Such configurations will yield electron-nucleus collisions with per nucleon centre-of-mass energies 0.8-2.2 TeV and luminosities...
Using the LHCb and ALICE detectors in the fixed-target mode at the LHC offers unprecedented possibilities to study the quark, gluon and heavy-quark content of the proton and nuclei in the poorly known region of the high-momentum fractions. We review our projections for studies of Drell-Yan, charm, beauty and quarkonium production with both detector set-ups used with various nuclear targets and...
The accumulation of a large amount of new experimental data at an impressive rate at present and future collider experiments has led to important questions concerning data storage and organization, their public access and usability, as well as their effective and efficient usage in order to discriminate between different theories. For the last thirty years, the HEPData database has been the...
The light-cone definition of Parton Distribution Functions (PDFs) does not allow for a direct ab initio determination employing methods of Lattice QCD simulations that naturally take place in Euclidean spacetime. In this presentation we focus on pseudo-PDFs where the starting point is the equal time hadronic matrix element with the quark and anti-quark fields separated by a finite distance. ...
In this talk, I will discuss the computation of collinear PDFs in the framework of Lattice QCD, using the so-called quasi-PDF approach introduced by Xiangdong Ji in 2013 and intensively developed thereafter. We employed twisted mass fermions with light quark mass set to its physical value. The relevant matrix elements obtained on the lattice were non-perturbatively renormalized and converted...
A fixed-target experiment using the LHC beams with an (un)polarized target would offer a unique opportunity to study the 3-dimensional (3D) and spin structure of the nucleon. Recent studies have shown that a number of spin and azimuthal asymmetries are large enough to be precisely measured, allowing to constrain several non-perturbative functions which encode the internal structure of the...
The LHCSpin project aims to bring both unpolarized and polarized physics at the LHC through the installation of a gaseous fixed target at the upstream end of the LHCb detector. The forward geometry of the LHCb spectrometer is perfectly suited for the reconstruction of particles produced in fixed-target collisions. The fixed-target configuration, with center-of-mass energies ranging from √s=115...
In this contribution we briefly discuss an ongoing phenomenological programme on quarkonium production in unpolarised and polarised proton-proton collisions in a fixed target setup at LHCb, the LHCSpin project.
Within a TMD approach, we will consider in particular: the relative role of the NRQCD color-singlet and color-octet production mechanisms, both for unpolarised and polarised quarkonium...
We describe two recent ideas to probe gluon TMDs in electron-proton collisions using quarkonium production. In the first one, we study the semi-inclusive production of a j/psi or upsilon meson in deep-inelastic scattering off a (un)polarized proton. In the regime where the small transverse momentum of the quarkonium is much smaller than the virtuality of the process, the cross section is...
A future EIC with forward detectors would enable measurements of DIS on
the deuteron with detection of a forward proton/neutron (spectator tagging) over a wide kinematic range. Spectator tagging controls the nuclear configuration during the DIS process and permits an accurate differential treatment of nuclear effects. When combined with deuteron polarization, the method enables next-generation...

leading to significant improvements in our understanding
of strong interactions. After a brief summary of the planned
research in hadron partonic structure and hadron spectroscopy,
the presentation will focus on two...
The new planned QCD facility at the M2 beam line of the CERN SPS will have a broad experimental programme addressing fundamental issues leading to significant improvements in our understanding of strong interactions. The presentation will be focused on the Drell-Yan programme, which aims to make a major step forward in the determination of the nearly unknown pion and kaon parton distribution...
The production of light vector mesons $V=\rho,\omega, \varphi, K^*$ off nuclei targets with pion, kaon and muon beams at the new planned QCD facility at the M2 beam line of the CERN SPS will be presented. Whereas in the charge exchange reaction $\pi^-+p\to V+n$ vector mesons are produced mainly longitudinally polarized (helicity $\lambda=0$) the investigation of
their production off...
The proton radius can be determined by measuring the slope of the electric form factor at small squared four-momentum transfer $Q^2$. Numerous elastic-scattering and laser-spectroscopy measurements of the proton radius have been performed with contradicting results, the so-called proton radius puzzle. We propose to measure the proton radius in high-energy elastic muon-proton scattering at the...
The shear forces in deuteron are related to tensor polarization and may be studied in both exclusive and inclusive processes. They are related to sum rules for tensor spin structure functions and provide the new probe of gravity coupling to quarks and gluons and Equivalence Principle (EP). The HERMES data are compatible with validity of EP separately to quarks and gluons. The more accurate...
The Large Hadron-electron Collider (LHeC) is a proposed upgrade of the LHC at CERN. An ERL will provide electrons to collide with the HL-LHC, HE-LHC and the FCC-hh proton and ion beams to achieve per nucleon centre-of-mass energies 1.3-3.5 (0.8-2.2) TeV and luminosities $\sim 10^{34(33)}$ cm$^{-2}$s$^{-1}$. Such a machine offers the opportunity to build a state-of-the-art HEP detector to be...
The Electron-Ion Collider (EIC) project is rapidly marching towards its approval stage in the US.
The anticipated design goals of the collider, with the luminosity 2-3 orders of magnitude higher than that at HERA, polarized electron and proton beams, as well as nuclear beams from light to heavy species, pose several technological challenges by itself.
Equally demanding are the requirements...
After an introduction to the EIC (parameters, physics goals, and status)
and a quick overview of the various detector concepts being developed for the EIC,
I will introduce the TOPSiDE detector concept. TOPSiDE aims a the detection and
identification of all particles created in electron-proton/ion collisions at the EIC
while achieving the best possible momentum/energy resolution....
Initial simulations investigating using the RHIC-EIC proton beam as the drive beam in a plasma wakefield acceleration experiment are presented. The proton beam enters the plasma and undergoes self-modulation, forming a series of microbunches. These microbunches resonantly drive electron density perturbations within the plasma, exciting a longitudinal electric field with accelerating gradients...

Its applications are multiple, going from accelerator science as a proof of concept for a multipass high-current energy recovery machine, to component testing, BSM, EW, hadron and nuclear physics with electrons and photon...
In this contribution I will provide an overview of the physics possibilities in the future DIS machines: EIC, LHeC and FCC-eh.
Understanding the properties of nuclear matter and its emergence through the underlying partonic structure and dynamics of quarks and gluons requires a new experimental facility in hadronic physics known as the Electron-Ion Collider (EIC). A US-based facility capable of colliding high-energy polarized electron and ion beams at high luminosity has been envisaged for a long time and articulated...

Recently, an Electron-Ion Collider was proposed in China based on the High-Intensity Heavy Ion Accelerator Facility (HIAF) which is currently under construction. The first phase of EicC will be an e-p/e-A collider with center-of-mass energy around 10-20 GeV for e-p. Both electron and proton (light nucleus) beams will be polarized with a luminosity of 1-5x10$^{33}$ cm$^{−2}$s$^{−1}$. EicC will...
The DIS of leptons with different energy on hadrons, light and heavy nuclei is dicsussed. It should allow one to explore the transitions between different ways of description of QCD matter and dualities between them.
In particular, the interplay between the description of azimuthal asymmetries in terms of Wigner functions and collective flows and corresponding duality between the statistical...
A high-energy high-luminosity polarized electron-ion collider (EIC) is the Nuclear Science Advisory Committee's highest priority for new facility construction. A dedicated $e+A$ Monte Carlo event generator is especially crucial during the process of identifying observables and the experimental needs they would pose to detector designs. The JETSCAPE collaboration recently released version 1.0...
The goal of the planned high-energy high-luminosity polarized electron-ion collider (EIC) is a detailed understanding of the QCD dynamics that underlie the nucleons and nuclei. With advances in experimental technique and theoretical understanding over the past several decades, jets have become precision tools in the exploration of QCD in collider environments. Therefore, precision jet...
A technique has been recently proposed to achieve a control of the neutrino targets and fluxes comparable to electron scattering experiments. In particular, it allows precise measurements of high statistics samples of (anti)neutrino-hydrogen interactions and of various nuclear targets. The planned high intensity LBNF/DUNE beams give access to a broad mixture of measurements of electroweak...
