简介
A systematic study is presented for centrality, transverse momentum (), and pseudorapidity () dependence of the inclusive charged hadron elliptic flow () at midrapidity () in collisions at , 11.5, 19.6, 27, and 39 GeV. The results obtained with different methods, including correlations with the event plane reconstructed in a region separated by a large pseudorapidity gap and four-particle cumulants (), are presented to investigate nonflow correlations and fluctuations. We observe that the difference between and is smaller at the lower collision energies. Values of , scaled by the initial coordinate space eccentricity, v2/ɛ, as a function of are larger in more central collisions, suggesting stronger collective flow develops in more central collisions, similar to the results at higher collision energies. These results are compared to measurements at higher energies at the Relativistic Heavy Ion Collider ( and 200 …
