We present a possible explanation for this phenomenon based on the existence of collective effects. String Fusion Model results are compared to the data and predictions are also presented.Latex, 10 pages, 3 Postscript figuresHigh Energy Physics - PhenomenologyFast antibaryon production: A new collective effect in Pb-Pb collisions?text
