| الوصف: | Chiral Magnetic Effect (CME) is a phenomenon in which electric charge is separated by a strong magnetic field from local domains of chirality imbalance in quantum chromodynamics. The CME-sensitive, azimuthal correlator difference $\Delta\gamma$ between opposite-sign (OS) and same-sign (SS) charged hadron pairs is contaminated by a major physics background proportional to the particle elliptic anisotropy ($v_2$). The CME signal, on the other hand, contributes to the difference in the pair elliptic anisotropies between OS and SS pairs ($\Delta v_{2,\rm pair}$). We investigate $\Delta v_{2,\rm pair}$ and found its sensitivity to CME to be similar to that of the $\Delta\gamma$ observable. Comment: 6 pages, 7 figures |
