Non-identical particle femtoscopy at sqrt(s_NN)=200 AGeV in hydrodynamics with statistical hadronization

Adam Kisiel

摘要:

非全同粒子飞秒显微术不仅可以探测发射系统的大小,还可以探测不同质量粒子之间的发射不对称性,这种不对称性与物质的集体行为密切相关。我们应用该技术对sqrt{s_{NN} }=200 AGeV重离子碰撞的{ \tt THERMINATOR}+Lhyquid模型进行了模拟。我们提出了所有常见的对组合的预测,并讨论其解释。重点是从非全同粒子关联中提取关于物质集体行为的独特信息,并理解来自强子共振衰变的粒子的作用。我们还详细介绍了应用于重离子碰撞数据的非全同粒子飞秒技术的技术方面。我们列出了系统误差的来源,来自方法本身和通常的假设。我们描述了强大的分析方法,并讨论其局限性。

英文摘要:

Non-identical particle femtoscopy probes not only the size of the emitting system, but also the emission asymmetries between particles of different mass, which are intimately related with the collective behavior of matter. We apply the technique to the simulations from the {\tt THERMINATOR}+Lhyquid model of the heavy-ion collisions at sqrt{s_{NN}}=200 AGeV. We present predictions for all common pair combinations and discuss their interpretation. Emphasis is put on extracting unique information about collective behavior of matter from the non-identical particle correlations and understanding the role of particles coming from decays of hadronic resonances. We also present, in detail, the technical aspects of the non-identical particle femtoscopy technique applied to data from the heavy-ion collisions. We list the sources of systematic errors coming from the method itself and the usual assumptions. We describe robust analysis methods and discuss their limitations.
