Effects of strong color fields on baryon dynamics

We calculate the antibaryon-to-baryon ratios, (p) over bar /p, (Lambda) over bar/Lambda, (Xi) over bar/Xi, and (Omega) over bar/Omega for Au + Au collisions at RHIC (rootS(NN) = 200 GeV). The effects of strong color fields associated with an enhanced strangeness and diquark production probability and with an effective decrease of formation times are investigated. Antibaryon-to-baryon ratios increase with the color field strength. The ratios also increase with the strangeness content \S\. The netbaryon number at midrapidity considerably increases with the color field strength while the netproton number remains roughly the same. This shows that the enhanced baryon transport involves a conversion into the hyperon sector (hyperonization) which can be observed in the (Lambda - (Lambda) over bar)/(p - (p) over bar) ratio.
