Abstract
This paper reports results for directed flow and elliptic flow of charged particles in Cu Cu collisions at GeV at the Relativistic Heavy Ion Collider. The measurements are for the 0–60 most central collisions, using charged particles observed in the STAR detector. Our measurements extend to 22.4-GeV Cu Cu collisions the prior observation that is independent of the system size at 62.4 and 200 GeV and also extend the scaling of with to this system. The measured in Cu Cu collisions is similar for throughout the range 22.4 to 200 GeV. We also report a comparison with results from transport model (ultrarelativistic quantum molecular dynamics and multiphase transport model) calculations. The model results do not agree quantitatively with the measured , and .
