Query: Can shadowing mimic the QCD phase transition?   The directed flow of protons is studied in the quark-gluon string model as a
function of the impact parameter for S+S and Pb+Pb reactions at 160 AGeV/c. A
significant reduction of the directed flow in midrapidity range, which can lead
to the development of the antiflow, is found due to the absorption of early
emitted particles by massive spectators (shadowing effect). This effect can
mimic the formation of the quark-gluon plasma (QGP). However, in the absorption
scenario the antiflow is stronger for the system of light colliding nuclei than
for the heavy ones, while in the case of the plasma creation the effect should
be opposite.
