Query: Initial conditions for RHIC collisions   An Effective String Rope Model (ESRM) for heavy ion collisions at RHIC
energies is presented. Our model takes into account baryon recoil for both
target and projectile, arising from the acceleration of partons in an effective
field, produced in the collision. The typical field strength (string tension)
for RHIC energies is about $5-12 GeV/fm$, what allows us to talk about "string
ropes''. Now we describe an "expanding final streaks" scenario, in contrast to
a "non-expanding final streaks" discussed in our works before. The results show
that a QGP forms a tilted disk, such that the direction of the largest pressure
gradient stays in the reaction plane, but deviates from both the beam and the
usual transverse flow directions. The produced initial state can be used as an
initial condition for further hydrodynamical calculations. Such initial
conditions lead to the creation of a third flow component.
