| 英文摘要 | Elliptic flow splitting Delta v(2) between (u) over bar and u quarks as well as between pi(-) and pi(+) in midcentral Au + Au collisions at root sNN = 200 GeV is studied, based on the framework of an extended multiphase transport model with the partonic evolution described by the chiral kinetic equations of motion. Within the available statistics, the slope of Delta v(2) between (u) over bar and u quarks with respect to the electric charge asymmetry A(ch) from the linear fit is found to be negative, due to the correlation between the velocity and the coordinate in the initial parton phase-space distribution. Simulations with the magnetic field in QGP overestimate the splitting of the spin polarization between Lambda and (Lambda) over bar observed experimentally, with the latter more consistent with results under the magnetic field in vacuum. Considering the uncertainties from the magnetic field, the quark-antiquark vector interaction, and the hadronization, as well as the hadronic evolution, our study shows that the experimentally observed positive slope of Delta(v)(2) with respect to A(ch) is not likely due to the chiral magnetic wave. |
