Constraining the chiral magnetic effect using spectator and participant planes across Au+Au and isobar collisions at $\sqrt{s_{{}_{\mathrm{NN}}}}=200$ GeV

Bang-Xiang Chen, Xin-Li Zhao, Guo-Liang Ma

We investigate the chiral magnetic effect (CME) in relativistic heavy-ion collisions through an improved two-plane method analysis of the $\hat{I}”{\hat{I}}^3$ observable, probing $\mathcal{C}\mathcal{P}$-…
