Аннотация
The elliptic (v2) and triangular (v3) azimuthal anisotropy coefficients in central 3He thorn Au, d thorn Au, and p thorn Au collisions atffiffiffiffiffiffiffi p 1/4 200 GeV are measured as a function of transverse momentum (pT) at sNN midrapidity (j and eta;j < 0.9), via the azimuthal angular correlation between two particles both at j and eta;j < 0.9. While the v2opT thorn values depend on the colliding systems, the v3 opT thorn values are system independent within the uncertainties, suggesting an influence on eccentricity from subnucleonic fluctuations in these small -sized systems. These results also provide stringent constraints for the hydrodynamic modeling of these systems.
