摘要

相对论性重离子碰撞中奇异夸克的产生被用作诊断工具，也是QGP形成的标志。QGP介质中的强相互作用会产生正常物质中不存在的奇异夸克和反夸克。原因是在它们产生后不久，它们通过弱相互作用发生衰变。它独特的质量预计接近质子、中子和其他强子变成夸克的温度。因此，这些奇异夸克、反夸克对物质的定义状态的条件、结构和动力学非常敏感。如果存在大量的奇异夸克，就可以说达到了定态。在这个程序中，我们将讨论不同的超子产率($\Lambda , \Xi , \Omega $)计算使用AMPT和UrQMD模型。

Strange Particle Production in Au $+$ Au Collisions at $\sqrt{s_{NN}} = 14.6$ Gev Using AMPT and UrQMD

Strange quark production in relativistic heavy-ion collisions is used as a diagnostic tool as well as a signature for QGP formation. Strong interactions in the QGP medium generate strange quarks and antiquarks which don’t exist in normal matter. The reason being shortly after their production, they undergo decay via weak interactions. Its unique mass which is expected close to the temperature at which protons, neutrons and other hadrons turn into quarks. Hence, these strange quarks, antiquarks are sensitive to the conditions, structure and dynamics of the deconfined state of matter. It can be said that the deconfined state is reached if there is an abundance of strange quarks. In this proceedings we are going to discuss about the different hyperon yields ($\Lambda , \Xi , \Omega $) calculated using AMPT and UrQMD model.

期刊介绍： The journal Few-Body Systems presents original research work – experimental, theoretical and computational – investigating the behavior of any classical or quantum system consisting of a small number of well-defined constituent structures. The focus is on the research methods, properties, and results characteristic of few-body systems. Examples of few-body systems range from few-quark states, light nuclear and hadronic systems; few-electron atomic systems and small molecules; and specific systems in condensed matter and surface physics (such as quantum dots and highly correlated trapped systems), up to and including large-scale celestial structures. Systems for which an equivalent one-body description is available or can be designed, and large systems for which specific many-body methods are needed are outside the scope of the journal. The journal is devoted to the publication of all aspects of few-body systems research and applications. While concentrating on few-body systems well-suited to rigorous solutions, the journal also encourages interdisciplinary contributions that foster common approaches and insights, introduce and benchmark the use of novel tools (e.g. machine learning) and develop relevant applications (e.g. few-body aspects in quantum technologies).
