Abstract
In this paper, new measurements of anisotropic flow ( v 1 , v 2 ) for identified particles such as pions and protons in Cu + Au collisions at s N N = 200 GeV and U + U collisions at s N N = 193 GeV are reported. The anisotropic flow is studied as a function of p T and centrality in these two collision systems. In ultra-central U + U collisions (0–2% centrality), v 2 of protons shows a weak p T dependence for p T < 1.0 GeV/c . A positive v 1 for charged pions is observed for p T > 1 GeV/c with respect to the first-order event plane, the angle of which is determined by the Au-going spectators. The scaling of identified particle v 2 with the number of valence quarks ( n q ) has been observed in these two collision systems, with the transverse kinetic energy.
