We discuss the helicity polarization which can be locally induced from both vorticity and helicity charge in non-central heavy ion collisions. Helicity charge redistribution can be generated in viscous fluid and contributes to azimuthal asymmetry of the polarization along global angular momentum or beam momentum. We also discuss on detecting the initial net helicity charge from topological charge fluctuation or initial color longitudinal field by the helicity polarization correlation of two hyperons and the helicity alignment of vector mesons in central heavy ion collisions.

  1. Experimental Search for the Chiral Magnetic Effect in Relativistic Heavy-Ion Collisions: A Perspective

    nucl-ex 2025-02 conditional novelty 3.0 of 10

    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.
