Resolving the Antibaryon-Production Puzzle in High-Energy Heavy-Ion Collisions

We argue that the observed antiproton production in heavy-ion collisions at CERN-SPS energies can be understood if (contrary to most sequential scattering approaches) the backward direction in the process pP<-->n(pi) (with n = 5-6) is consistently accounted for within a thermal framework. Employing the standard picture of subsequent chemical and …
