abstract
We show that fluctuations in elliptic anisotropy in heavy-ion collisions can be used to significantly reduce the contribution of transverse-momentum conservation, and of all background effects independent on the orientation of the reaction plane, from an observable of the chiral magnetic effect. We argue that for a given impact parameter, the magnetic field is approximately independent of the fluctuating shape of the fireball.

Experimental Search for the Chiral Magnetic Effect in Relativistic Heavy-Ion Collisions: A Perspective
The chiral magnetic effect in heavy-ion collisions remains unconfirmed, with current data giving a 2.9-sigma hint in Au+Au and an upper limit near 10% in isobar collisions.
