This local workshop aims at gathering the low energy nuclear experimental and theoretical communities, with the high energy QCD experimental LHC community, in order to explore the opportunities offered by new observables measured at the LHC in order to constrain the structure of the nucleus.

The LHC has recently completed its operations after almost 2 decades of successful running, providing proton-proton, heavy-ion and recently light-ion collisions at unprecedented energies. While preparing for the future high-luminosity era, CERN is investigating which ions to collide next. This workshop is
