One of the striking features of particle production at high beam energies is the near equal abundance of matter and antimatter in the central rapidity region. In this paper we study how this symmetry is reached as the beam energy is increased. In particular, we quantify explicitly the energy dependence of the approach to matter/antimatter symmetry in proton-proton and in heavy-ion collisions. Expectations are presented also for the production of more complex forms of antimatter like antihypernuclei.

  1. $\Lambda$(1520) as a probe of resonance-driven deuteron formation at the LHC

    hep-ex 2026-06 unverdicted novelty 7.0

    Simulations show a peak in the proxy mass M_(d/2)K only when deuterons form by coalescence of protons from Λ(1520) decays, not in thermal models.

  2. More uses for Thermal Models

    hep-ph 2026-02 unverdicted novelty 5.0

    Combinations of particle yields enable parameter-free tests of thermal models and extraction of μ_B/T, μ_S/T, μ_Q/T from RHIC BES data, matching published parameters and allowing predictions for other particles and nuclei.
