Chiral magnetic effect in isobaric collisions

We give a numerical simulation of the generation of the magnetic field and the charge-separation signal due to the chiral magnetic effect (CME) — the induction of an electric current by the magnetic field in a parity-odd matter — in the collisions of isobaric nuclei, ${}_{44}^{96}$Ru + ${}_{44}^{96}$Ru and ${}_{40}^{96}$Zr + ${}_{40}^{96}$Zr, at $\sqrt{s_{\mathrm{N}\mathrm{N}}}=200$ GeV. We show that such collisions provide an ideal tool to disentangle the CME signal from the possible elliptic-flow driven background effects. We also discuss some other effects that can be tested by using the isobaric collisions.
