HSD模型中重离子碰撞的宇称奇效应
Parity-odd effects in heavy-ion collisions in the HSD model
摘要：
利用强子弦动力学（HSD）模型研究了非中心重离子碰撞中的螺旋度分离效应。在反应中心周围的小体积中，在网格上进行计算机模拟以计算速度和流体动力学螺旋度。对于不同的碰撞参量和不同的计算方法，观察到了流体动力螺旋度的时间依赖性。与类似的早期工作进行比较。一个新的量被用来分析粒子的最终状态。它用于探测末态中的p奇效应。
英文摘要：
Helicity separation effect in non-central heavy ion collisions is investigated using the Hadron-String Dynamics (HSD) model. Computer simulations are done to calculate velocity and hydrodynamic helicity on a mesh in a small volume around the center of the reaction. The time dependence of hydrodynamic helicity is observed for various impact parameters and different calculation methods. Comparison with a similar earlier work is carried out. A new quantity is used to ananlyze particles in the final state. It is used to probe for p-odd effects in the final state.
