Antiflow of nucleons at the softest point of the equation of state

Abstract: We investigate flow in semi-peripheral nuclear collisions at AGS and SPS energies within macroscopic as well as microscopic transport models. The hot and dense zone assumes the shape of an ellipsoid which is tilted by an angle Θ with respect to the beam axis. If matter is close to the softest point of the equation of state, this ellipsoid expands predominantly orthogonal to the direction given by Θ. This antiflow component is responsible for the previously predicted reduction of the directed transverse momentu… Show more

“…Such tilted expansion gives rise to anti-flow [6] (or a 3 rd flow component [7]). The anti-flow is perpendicular to the source surface, and is in the opposite direction to the bouncing-off motion of nucleons.…”

“…The development of flow is closely related to the pressure gradients, and thus, to the equation of state of the nuclear matter formed in the collision [9,10]. Collective flow is also believed to be a promising signal to detect the creation of the quark-gluon plasma [11][12][13]. An increased attention to collective flow has also resulted in significant improvements in the techniques and methods of analysis and presentation of the experimental data.…”

“…The full (3+1)-dimensional calculation of relativistic hydrodynamical equation has already been done by Rischke et al [21] and Brachmann et al [22]. Rischke pointed out that the minimum of the excitation function of directed flow suggests the existence of the phase transition [21].…”
