- Аннотация: We present high-precision measurements of elliptic, triangular, and quadrangular flow 𝑣2, 𝑣3, and 𝑣4, respectively, at midrapidity for identified hadrons 𝜋, 𝑝, 𝐾, 𝜑, 𝐾𝑠, Λ as a function of centrality and transverse momentum in Au+Au collisions at the center-of-mass energy √𝑠𝑁𝑁=200 GeV. We observe similar 𝑣𝑛 trends between light and strange mesons which indicates that the heavier strange quarks flow as strongly as the lighter up and down quarks. The number-of-constituent-quark scaling for 𝑣2, 𝑣3, and 𝑣4 is found to hold within statistical uncertainty for 0–10%, 10–40%, and 40–80% collision centrality intervals. The results are compared to several viscous hydrodynamic calculations with varying initial conditions, and could serve as an additional constraint to the development of hydrodynamic models.
