FAIR的奇异波动和MEMO生产
Strangeness fluctuations and MEMO production at FAIR
摘要：
本文应用输运-流体动力学耦合模型讨论了FAIR装置上Pb+Pb反应中多奇异亚稳天体的产生。除了对这些粒子的产额进行预测外，我们还能够计算粒子依赖的快度和动量分布。我们认为FAIR能区是寻找多奇异重子天体的最佳场所（由于重子密度高，有利于奇异性的升华）。此外，我们还展示了奇异性和重子密度涨落的结果。使用UrQMD模型，我们计算相空间中的奇异分离，这可能会导致增强生产的MEMO相比，假设全球热化的模型。
英文摘要：
We apply a coupled transport-hydrodynamics model to discuss the production of multi-strange meta-stable objects in Pb+Pb reactions at the FAIR facility. In addition to making predictions for yields of these particles we are able to calculate particle dependent rapidity and momentum distributions. We argue that the FAIR energy regime is the optimal place to search for multi-strange baryonic object (due to the high baryon density, favouring a distillation of strangeness). Additionally, we show results for strangeness and baryon density fluctuations. Using the UrQMD model we calculate the strangeness seperation in phase space which might lead to an enhanced production of MEMOs compared to models that assume global thermalization.
