Deuteron yields from heavy-ion collisions at energies available at the CERN Large Hadron Collider: Continuum correlations and in-medium effects

To explain the production of light nuclei in heavy-ion collisions at extreme energies, we focus on deuteron case. A Gibbs ensemble chemical freeze-out is a prerequisite to investigate non-equilibrium evolution expanding fireball. Quantum statistical approaches allow describe correlations including bound state formation strongly interacting and hot system. We consider virial approach evaluate proton-neutron correlations. In generalization treatment protons pionic matter (pion-proton puzzle), influence pion environment deuteron-like evaluated using data for pion-deuteron scattering phase shifts. Calculated yields are compared with ones observed LHC.
