Abstract: (Elsevier)

We propose that measurements of the antiproton and proton yields in ultrarelativistic nucleus-nucleus collisions can provide a sensitive probe of the spacetime evolution in these reactions. We estimate the antiproton suppression expected due to annihilation processes for collisions in the energy range s =10–200 A GeV .

nucleus nucleus: nuclear reaction
scattering: heavy ion
nuclear reaction: central region
baryon: hadroproduction
yield: (p anti-p)
baryon antibaryon: annihilation
