英文摘要 | High-energy heavy-ion collisions produce abundant hyperons and nucleons. A dynamical coalescence model coupled with the ART model is employed to study the production probabilities of light clusters, deuteron (d), triton (t), helion ((3)He), and hypertriton ((3)(A)H) at subthreshold energy of A production (approximate to 1 GeV per nucleon). We study the dependence on the reaction system size of the coalescence penalty factor per additional nucleon and entropy per nucleon. The Strangeness Population Factor (S(3) =(3)(A)H/((3)He x A/p)) shows an extra suppression of hypertriton comparing to light clusters of the same mass number. This model predicts a hypertriton production cross-section of a few mu b in (36)Ar+(36)Ar, (40)Ca+(40)Ca and (56)Ni+(56)Ni in 1 A GeV reactions. The production rate is as high as a few hypertritons per million collisions, which shows that the fixed-target heavy-ion collisions at CSR (Lanzhou/China) at A subthreshold energy are suitable for breaking new ground in hypernuclear physics. |
