Abstract
This paper reports results for directed flow v[subscript 1] and elliptic flow v[subscript 2] of charged particles in Cu + Cu collisions at √[superscript s][subscript NN]=22.4 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 v[subscript 1] is independent of the system size at 62.4 and 200 GeV and also extend the scaling of v[subscript 1] with η/ybeam to this system. The measured v2(p[subscript T]) in Cu + Cu collisions is similar for √[superscript s][subscript NN] 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 [subscript 1] (η), [subscript 2](p[subscript T]), and [subscript 2](η).
