Heavy-ion collisions are powerful tools for studying hypernuclear physics. We develop a dynamical coalescence model coupled with an ART model (version 1.0) to study the production rates of light nuclear clusters and hypernuclei in heavy-ion reactions, for instance, the deuteron (d), triton (t), helium (3He), and hypertriton (3ΛH) in minimum bias (0–80% centrality) 6Li + 12C reactions at beam energy of 3.5A GeV. The penalty factor for light clusters is extracted from the yields, and the distributions of h angle of particles, which provide direct suggesetions about the location of particle detectors in the near future facility—High Intensity heavy-ion Accelerator Facility (HIAF) are investigated. Our calculation demonstrates that HIAF is suitable for studying hypernuclear physics.
