论文摘要
美容夸克被认为是相对论重型离子碰撞中强烈相互作用媒介的最佳探针之一，因为它们主要是通过初始硬散射产生的。 B Meson生产的测量提供了有关美容夸克扩散以及中等能量损失的风味依赖性的信息。在这些研究中，阐明强龙机制对于理解美容夸克的运输特性至关重要。 $ b^{0} _ {s} $生产的测量可以阐明介质中美容重组的机制，并提供有关夸克 - 格鲁恩等离子体中陌生性增强的信息。在本次演讲中，我们将使用2018年记录的数据对CMS检测器的PBPB碰撞中的$ B^{0} _ {s} $与$ B^+$ Mesons的比率进行新的测量。
Beauty quarks are considered as one of the best probes of the strongly interacting medium created in relativistic heavy-ion collisions because they are predominantly produced via initial hard scatterings. Measurements of B meson production provide information about the diffusion of beauty quarks and the flavor dependence of in-medium energy loss. In these studies, clarifying the hadronization mechanism is crucial for understanding the transport properties of beauty quarks. Measurements of $B^{0}_{s}$ production can shed light on the mechanisms of beauty recombination in the medium and provide information about strangeness enhancement in the quark-gluon plasma. In this talk, we will present a new measurement of the ratio of $B^{0}_{s}$ to $B^+$ mesons in PbPb collisions at 5.02 TeV with the CMS detector, using data recorded in 2018.
