J. Rafelski et M. Danos, STRANGENESS FLOW DIFFERENCE IN NUCLEAR COLLISIONS AT 15A AND 200A GEV, Physical review. C. Nuclear physics, 50(3), 1994, pp. 1684-1687
We show existence of an important difference between strange-particle
production in Si-Au collisions at 15A GeV (AGS) and in S-A collisions
at 200A GeV (CERN), with A = 32 and A = 0(200).
