Is the Chiral Magnetic Effect fast enough?

Understand

It depends: While we find within holography that the lifetime of the magnetic field for collider energies like the ones achieved at RHIC is long enough to build up the chiral magnetic current, the lifetime of the magnetic field at LHC seems to be too short.

• We study the real time evolution of the chiral magnetic effect out-of-equilibrium in strongly coupled holographic gauge theories.
• We consider the backreaction of the magnetic field onto the geometry and monitor pressure and chiral magnetic current.
• Our findings show that generically at small magnetic field the pressure builds up faster than the chiral magnetic current whereas at strong magnetic field the opposite is true.
