abstract
At the very first stage of an ultra-relativistic nucleus-nucleus collision new particles are produced in individual nucleon-nucleon collisions. In the transverse plane, all particles from a single $NN$ collision are initially located at the same position. The subsequent transverse radial expansion of the system creates strong position-momentum correlations and leads to characteristic rapidity, transverse momentum, and azimuthal correlations among the produced particles.

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.
