Beschreibungen/Notizen

• The first (v$even\atop{1}$), second (v2) and third (v3) harmonic coefficients of the azimuthal particle distribution at mid-rapidity, are extracted for charged hadrons and studied as a function of transverse momentum (pT) and mean charged particle multiplicity density $\langle$Nch$\rangle$ in U+U ($\sqrt{s_ {NN}}$ = 193 GeV), Au+Au, Cu+Au, Cu+Cu, d+Au and p+Au collisions at $\sqrt{s_ {NN}}$ = 200 GeV with the STAR Detector. For the same $\langle$Nch$\rangle$, the v$even\atop{1}$ and v3 coefficients are observed to be independent of collision system, while v2 exhibits such a scaling only when normalized by the initial-state eccentricity (ε2). The data also show that ln(v2/ε2) scales linearly with $\langle$Nch$\rangle$-1/3. Finally, these measurements provide insight into initial-geometry fluctuations and the role of viscous hydrodynamic attenuation on vn from small to large collision systems.
