I will review the possibility offered by the LHC beams in the fixed-target mode to advance our knowledge on quarkonium physics.
The LHCb experiment has the unique capability to operate as both a collider experiment and a fixed-target experiment. This talk will discuss what was learned from the first phase of the fixed-target program at LHC and what can be expected from the upgraded system, which will begin providing high-statistics fixed target data when the LHC resumes operation.
During the past 40 years, the production of pairs of the J/psi mesons in high energy hadron collisions has been studied by several experiments. Despite the experimental and theoretical efforts, the origin of the process and the relative weight of different production mechanisms still remain unknown. Depending on the energy scale the double J/psi production can be described by single- and...
Interactions with hadrons contribute to the suppression of quarkonium production observed in heavy-ion collisions. It is difficult to disentangle such cold nuclear matter effect from the effect of Debye-like screening of color charges in QGP, created in these collisions. Femtoscopic correlations of J/$\psi$-hadron allow to directly measure both elastic and inelastic scattering cross sections...
Open heavy flavor and quarkonium are valuable probes to identify the underlying QCD dynamics behind high multiplicity events at RHIC and LHC. The origin of collective flow found in small collision systems ($p+p$ and $p+A$) is still under debate, but the initial state interaction (gluon saturation) could be a significant source, giving high charged multiplicity. Recent LHC data on the event...
The study of quarkonium production in proton-nucleus collisions has been widely explored by all LHC experiment and represents a valuable tool in the investigation of cold nuclear matter (CNM) effects in relativistic heavy-ion collisions. Mechanisms such as the modification of the parton distribution functions in nuclei, the presence of a color glass condensate or the coherent energy loss of...
The LHCb collaboration has an unparalleled capability to reconstruct a wide range of conventional and exotic quarkonia states in small collision systems. We will discuss recent LHCb quarkonia results from high-multiplicity pp and pPb collisions, and what these probes teach us about the bound states of QCD, the effects of a nuclear medium, and the partonic structure of the nucleus
Double parton scattering (DPS) is a nucleon-nucleon scattering where two partons from each nucleon undergo two independent hard scattering processes. It is usually suppressed with respect to the traditional single parton scattering (SPS). However, under some conditions (like for quarkonia production), DPS contributions can be comparable or even dominate with respect to the SPS. The study of...
In this contribution, we discuss the possibilities and advantages of observing double parton scattering (DPS) in photon-proton interactions. In general, DPS measurements give access to double parton distribution functions of the protons. These distributions represent a novel and promising tool, to access the 3D partonic structure of the proton, complementary to TMDs and GPDs. In fact, dPDFs...
The Electron Ion collider (EIC) is a next generation accelerator which will provide answers to burning questions in the field of nuclear physics. The EIC is a very versatile collider with a wide range of beam energies, polarizations, and species, as well as high luminosity, all required to precisely image quarks and gluons in spatial and momentum space and their interactions, to explore the...
