Baryon Stopping in Heavy-Ion Collisions at E_{lab}= 2--160 GeV/nucleon

Abstract

It is argued that the experimentally observed baryon stopping may indicate (within the present experimental uncertainties) a non-monotonous behaviour as a function of the incident energy of colliding nuclei. This can be quantified by a midrapidity reduced curvature of the net-proton rapidity spectrum. The above non-monotonous behaviour reveals itself as a "zig-zag" irregularity in the excitation function of this curvature. The three-fluid dynamic calculations with a hadronic equation of state (EoS) fail to reproduce this irregularity. At the same time, the same calculations with an EoS involving a first-order phase transition into the quark-gluon phase do reproduce this "zig-zag" behaviour, however only qualitatively.

6 pages, 5 figures, the paper is essentially extended. This version will be published in Phys. Lett. B
