摘要：

Recent experiments at the Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) have demonstrated that there are excellent opportunities to produce light baryonic clusters of exotic matter (strange and antimatter) in ultrarelativistic ion collisions. Within the hybrid-transport ultrarelativistic quantum molecular dynamics (UrQMD) model, we show that the coalescence mechanism can naturally explain the production of these clusters in the ALICE experiment at LHC. As a consequence of this mechanism, we predict the rapidity domains where the yields of such clusters are much larger than the observed one at midrapidity. This new phenomenon can lead to unique methods for producing exotic nuclei.
