摘要：

Antiproton production from heavy ion collisions involves a strong competition between creation and annihilation mechanisms. Due to the high threshold energy, antiprotons mostly arise from the highest energy baryon-baryon collisions. We have identified a three-body screening mechanism which strongly reduces the subsequent absorption of antiprotons in the medium. We have used a relativistic cascade code to study this effect, and find that it is essential to obtaining good agreement with recent pBAR production data from Brookhaven experiment E802.
