Phys. Rev. Lett. 83, 1735–1738 (1999)Antihyperon Enhancement through Baryon Junction LoopsReceived 6 January 1999; published in the issue dated 30 August 1999 Midrapidity antihyperon (Y̅ ) production in nuclear collisions is studied using a new hadronic string mechanism. This mechanism of baryon junction-antijunction (JJ̅ ) loops is an extension of the baryon junction exchange mechanism recently proposed to explain valence baryon number transport. These loops are shown to enhance the Λ̅ , Ξ̅ , and Ω̅ as well as lead to long range rapidity correlations. Comparisons are made with recent observations of Pb+Pb→YY̅ X at the CERN Super Proton Synchrotron (SPS), and predictions are made for upcoming experiments. © 1999 The American Physical Society URL:
