It is easy to infer from simple coalescence model that light (anti)nuclei formed via coalescence of (anti)nucleons will also reflect similar difference in [v.sub.2] as the constituent nucleon and antinucleon. The difference in [v.sub.2] between particles and their antiparticles has been attributed to the chiral magnetic effect in finite baryon-density matter [81], different [v.sub.2] of produced and transported particles [82], different rapidity distributions for quarks and antiquarks [83], the conservation of baryon number, strangeness, and isospin [84], and different mean-field potentials acting on particles and their antiparticles [85-88].
