AbstractIn this paper we present STAR's measurements of nu(2) and nu(3) for charged kaons and pions at low transverse momentum range (0.15 < p(T) < 0.5 GeV/c), as a function of event charge asymmetry (A(ch)) in both U+U collisions at root s(NN) = 193 GeV and Au+Au collisions at root s(NN) = 200 GeV. We found that in 20% - 60% centrality, the ratio of slope parameters of Delta nu(3)(A(ch)) to that of Delta nu(2)(A(ch)), is +3 sigma below the predicted value (1/3) from local charge conservation at freeze-out, indicating that it is unlikely that such effect can have a significant contribution to the splitting of elliptic flow of charged pions as a function of A(ch). We also observed a smaller Delta nu(2)(A(ch)) slope for kaons relative to pions. Our measurements serve as important consistency checks for the phenomena suggested as the consequence of the chiral magnetic wave.
