abstract

Understanding the production mechanism of light (anti-)nuclei in high-energy nuclear collisions and cosmic rays has been a long-standing problem in nuclear physics. In the present study, we develop a stochastic method to solve the relativistic kinetic equations for light nuclei production from many-body reactions with the inclusion of their finite sizes. The present approach gives an excellent description of the deuteron and helium-3 data from central Au+Au (Pb+Pb) collisions at $\sqrt{s_{\rm NN}}$ $=$ $200~\rm GeV$ ($2.76~\rm TeV$). It can also naturally explain their suppressed production in $pp$ collisions at 7 TeV as a result of their finite sizes.

  1. Directed Flow of Protons and Deuterons in Xe+Cs(I) Collisions: Preliminary BM@N Data and THESEUS Modeling

    nucl-ex 2026-08 conditional novelty 4.0 of 10

    Comparing preliminary BM@N proton and deuteron directed flow with THESEUS shows good proton agreement and a slight deuteron overestimation, tentatively supporting thermodynamic light-nucleus formation.

  2. Study on the equation-of-state with light clusters and hypernuclei

    nucl-th 2025-09 conditional novelty 1.0 of 10

    A review of transport-model constraints on the nuclear equation of state from flow of protons, light clusters, and hypernuclei, concluding that soft momentum-dependent potentials fit few-GeV data best.
