摘要：We discuss the present collective flow signals for the phase transition to the quark-gluon plasma
(QGP) and the collective flow as a barometer for the equation of state (EoS). We emphasize the
importance of the flow excitation function from 1 to 50A GeV: here the hydrodynamicmodel has
predicted the collapse of the v1-flow at ∼ 10A GeV and of the v2-flow at ∼ 40A GeV. In the latter
case, this has recently been observed by the NA49 collaboration. Since hadronic rescattering
models predict much larger flow than observed at this energy, we interpret this observation as
potential evidence for a first order phase transition at high baryon density rB.
