"Review of the Experimental Search for the Chiral Magnetic Effect in Heavy-ion Collisions"

The quark-gluon plasma created in high-energy heavy-ion collisions has been conjectured to exhibit a spontaneous electric-charge separation in the direction of a strong magnetic field through the chiral magnetic effect (CME). The experimental confirmation of the CME in heavy-ion collisions will uncover fundamental aspects of strong interaction physics such as the QCD chiral symmetry restoration and the topological configurations of non-Abelian gauge fields. Over the past two decades, experiments at RHIC and the LHC have performed a series of charge-separation measurements in A+A collisions at various beam energies from the center-of-mass energy of 5.02 TeV down to 7.7 GeV, and in different collision systems including p+Au, p+Pb, d+Au, Cu+Cu, Au+Au, Pb+Pb and U+U collisions, as well as the recent isobaric Ru+Ru and Zr+Zr collisions. Multiple analysis methods have also been developed to manifest the charge separation effect and suppress the flow related background. In this talk, I will review the aforementioned results, summarize our current understanding, and provide an outlook on future analyses.
