用ALICE测量Pb-Pb碰撞中的手征磁效应

Measurements of the chiral magnetic effect in Pb--Pb collisions with ALICE

Md. Rihan Haque

摘要:

在ALICE装置上测量了$\sqrt{s_{\rm NN}}$ = 5.02 TeV的Pb-Pb碰撞中未知带电粒子的3粒子方位角关联.计算结果与$\sqrt{s_{\rm NN}}$ = 2.76 TeV的Pb-Pb碰撞结果进行了比较。我们没有观察到两个碰撞能量之间的电荷敏感的3粒子相关器($γ_{112}$)的显着差异。电荷依赖的混合谐波相关器($γ_{132}$)也提出了一个爆炸波模型,结合本地电荷守恒的预测和比较。

英文摘要:

We present the measurement of the charge-dependent 3-particle azimuthal correlation for unidentified charged particles in Pb--Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV in ALICE. The results are compared with corresponding results from Pb--Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV. We observe no significant difference in the charge-sensitive 3-particle correlator ($γ_{112}$) between the two collision energies. Charged-dependent mixed-harmonic correlator ($γ_{132}$) is also presented and compared with the predictions from a blast-wave model incorporating local charge conservation.
