Observation of Charge Asymmetry Dependence of Pion Elliptic Flow and the Possible Chiral Magnetic Wave in Heavy-Ion Collisions
Original language description
We present measurements of pi(-) and pi(+) elliptic flow, v(2), at midrapidity in Au + Au collisions at root s(NN) = 200, 62.4, 39, 27, 19.6, 11.5, and 7.7 GeV, as a function of event-by-event charge asymmetry, A(ch), based on data from the STAR experiment at RHIC. We find that pi(-) (pi(+)) elliptic flow linearly increases (decreases) with charge asymmetry for most centrality bins at root s(NN) = 27 GeV and higher. At root s(NN) = 200 GeV, the slope of the difference of v(2) between pi(-) and pi(+) asa function of A(ch) exhibits a centrality dependence, which is qualitatively similar to calculations that incorporate a chiral magnetic wave effect. Similar centrality dependence is also observed at lower energies.
