Baryon-anti-baryon Flavor Correlation in Quark Combination Models in Heavy Ion Collisions

Abstract

We extend the study of hadron yield correlation in combination models in a recent publication to baryon-anti-baryon flavor correlations in heavy ion collisions. We show that the universal behaviors of the anti-baryon to baryon yield ratios as functions of that of $K^{-}$ to $K^{+}$ are naturally explained. We study also the "mixed ratios" and propose other measurements that might be sensitive to the hadronization mechanism.
