摘要
ALICE 和 CMS 的最新研究结果表明，与基于一$^+$e$^-$对撞的模型预测相比，粲重子与介子的生成比在低反向动量下有所提高。人们提出了几种机制来理解这一现象。大型强子对撞机b和ALICE实验的新测量结果表明，在美部门也有类似的增强。我们利用最新收集的 LHC Run-3 数据，提出了依赖于事件形状的灵敏探测器，以区分所提出的 "美 "产生情况，并将这些数据与对粲的预测进行了比较。我们的结果将有助于加深对重味重子增强及其与一般重子增强关系的理论理解。
Event-activity-dependent beauty-baryon enhancement in simulations with color junctions
Recent results from ALICE and CMS show a low-transverse-momentum enhancement
of charm baryon-to-meson production ratios over model predictions based on
e$^+$e$^-$ collisions. Several mechanisms are proposed to understand this
phenomenon. New measurements by the LHCb and ALICE experiments show a similar
enhancement in the beauty sector. We explore this enhancement in terms of event
activity using the color-reconnection beyond leading order approximation model.
We propose sensitive probes relying on the event shape that will allow for the
differentiation between the proposed beauty-production scenarios using freshly
collected LHC Run-3 data, and we also compare these to predictions for charm.
Our results will contribute to a deeper theoretical understanding of the
heavy-flavor baryon enhancement and its relation to baryon enhancement in
general.
