The Chiral Magnetic Effect in Heavy-Ion Collisions

Abstract

We study the Chiral Magnetic Effect (CME) in heavy-ion collisions at a centre of mass energy of sqrt(2.76) TeV. We use a Blast-Wave Model incorporating Local Charge Conservation to simulate these collisions. We find good agreement with charge-independent global observables, such as charged particle yield spectra and the elliptic flow. By making use of Q-vectors we measure two charge-dependent correlations and find them to be a factor of approximately 10 and 7 times smaller than values measured by ALICE at the LHC, while being of similar shape. This indicates that at least part of the measured correlators can be explained by other sources, one of which could be the CME. Possible improvements of the model and, in addition, the research of the CME in general are discussed.
