Light anti-nuclei in pp collisions at the LHC: production by coalescence and interaction of anti-nucleons

A unified afterburner framework is presented to describe nucleon–nucleon final-state interactions and light-(anti)nuclei production via coalescence in high-energy measured in pp collisions at the LHC collisions. The model reproduces qualitatively light-(anti)nuclei spectra without fine-tuning of the model parameters, as well as correlation observables, and can be extended to beyond proton–proton collisions.
