相对论重离子碰撞中的电荷相关方位角关联和电磁效应

Charge-dependent Azimuthal Correlations in Relativistic Heavy-ion Collisions and Electromagnetic Effects

K. F. Liu

摘要:

我们提出了一个方案,最近观察到的电荷依赖的方位角相关的图案可以定性地理解。这是基于团簇图像和假设,即从碰撞核的重叠区域的表面向外流动的带电强子主要平行于反应平面移动。我们还指出,在相对论重离子碰撞的初始阶段,部分子产生过程中存在一个由瞬变磁场诱导的强电场,并讨论了它可能与该情景的关系。

英文摘要:

We propose a scenario where the pattern of the recently observed charge-dependent azimuthal correlations can be understood qualitatively. This is based on the cluster picture and the assumption that the charged hadrons that flow outward from the surface of the overlapping region of the colliding nuclei move primarily parallel to the reaction plane. We also point out the there is a strong electric field induced by the transient magnetic field during the parton production in the initial phase of the relativistic heavy-ion collision and discuss its possible relevance to the scenario.
