Electric charge separation in strong transient magnetic fields
Abstract
We discuss various mechanisms for the creation of an asymmetric charge fluctuation
with respect to the reaction plane among hadrons emitted in relativistic heavy-ion
collisions. We show that such mechanisms exist in both the hadronic gas and the partonic
phases of quantum chromodynamics. The mechanisms considered here all require the presence
of a strong magnetic field (the "chiral magnetic effect"), but they do not involve
parity or charge-parity violations. We analyze how a transient local electric current
fluctuation generated by the chiral magnetic effect can dynamically evolve into an
asymmetric charge distribution among final-state hadrons in momentum space. We estimate
the magnitude of the event-by-event fluctuations of the final-state charge asymmetry
owing to partonic and hadronic mechanisms. © 2010 The American Physical Society.
