论文摘要
提出和检查了扩展的$ r^{（2）} _ {ψ_{m}}（ΔS_{2}）$相关器的相关器的功效，以检测和表征四极电荷分离（$δS_{2} $）与载有perported chiral磁性波（CMW）相关联的倍增（$ΔS_{2}）。涉及不同程度的代理CMW信号的敏感性测试注入了模拟的多相传输模型（AMPT），表明$ r^{（2）} _ {ψ_{m}}}（m}}}}（ΔS_{2}）$ colorElator $ colorElator可为背景和cmw-driven提供可辨认的响应。这种区别可以通过$ r^{（2）} _ {ψ_{2}}（ΔS_{2}）$和$ r^{（2）_ {ψ_{ψ_{3}}}（ΔS_S_{2}）$ CORELARTOR，相对于第二个（ΔS）$（ΔS）$（ΔS）$（ΔS）$（ΔS）$（ΔS）$（ΔS）$（ΔS）$（ΔS）$（ΔS）$（ΔS）$（ΔS）$（ΔS）$（ΔS）$（ΔS）$（ΔS）$（ΔS）$（ΔS）$（ΔS）$ corelators，相对于第二个（ （$ψ_3$）事件飞机。这些测试还表明了一种灵敏度，可以允许CMW信号的强大实验表征。
The extended $R^{(2)}_{Ψ_{m}}(ΔS_{2})$ correlator is presented and examined for its efficacy to detect and characterize the quadrupole charge separation ($ΔS_{2}$) associated with the purported Chiral Magnetic Wave (CMW) produced in heavy-ion collisions. Sensitivity tests involving varying degrees of proxy CMW signals injected into events simulated with the Multi-Phase Transport Model (AMPT), show that the $R^{(2)}_{Ψ_{m}}(ΔS_{2})$ correlator provides discernible responses for the background- and CMW-driven charge separation. This distinction could aid identification of the CMW via measurements of the $R^{(2)}_{Ψ_{2}}(ΔS_{2})$ and $R^{(2)}_{Ψ_{3}}(ΔS_{2})$ correlators, relative to the second- ($Ψ_2$) and third-order ($Ψ_3$) event planes. The tests also indicate a level of sensitivity that would allow for robust experimental characterization of the CMW signal.
