Light nucleus and hypernucleus production at RHIC and LHC energies: a comparative study of phenomenological models

This document summarizes the work of the EMMI Rapid Reaction Task Force on ``Understanding light (anti)nuclei production at RHIC and LHC'', which took place at GSI on 8--12 April 2024. The meeting brought together experimentalists and theorists to discuss the current understanding of light-nuclei and hypernuclei production in high-energy hadronic collisions, with particular emphasis on statistical hadronization, coalescence, kinetic, and transport approaches. The discussions addressed the experimental status and the ability of different theoretical descriptions to reproduce the available measurements, as well as the connections between nuclear production, femtoscopic correlations, source sizes, nuclear wave functions, and the formation dynamics of loosely bound states. This document reviews the main experimental and theoretical developments presented during the RRTF, summarizes the key questions that emerged from the discussions, and identifies observables and future measurements that may help discriminate among different production mechanisms.

Future physics opportunities for high-density QCD at the LHC with heavy-ion and proton beams

The future opportunities for high-density QCD studies with ion and proton beams at the LHC are presented. Four major scientific goals are identified: the characterisation of the macroscopic long wavelength Quark-Gluon Plasma (QGP) properties with unprecedented precision, the investigation of the microscopic parton dynamics underlying QGP properties, the development of a unified picture of particle production and QCD dynamics from small (pp) to large (nucleus--nucleus) systems, the exploration of parton densities in nuclei in a broad ($x$, $Q^2$) kinematic range and the search for the possible onset of parton saturation. In order to address these scientific goals, high-luminosity Pb-Pb and p-Pb programmes are considered as priorities for Runs 3 and 4, complemented by high-multiplicity studies in pp collisions and a short run with oxygen ions. High-luminosity runs with intermediate-mass nuclei, for example Ar or Kr, are considered as an appealing case for extending the heavy-ion programme at the LHC beyond Run 4. The potential of the High-Energy LHC to probe QCD matter with newly-available observables, at twice larger center-of-mass energies than the LHC, is investigated.
