论文摘要
使用Pythia8事件生成器研究了$ \ sqrt {s}〜= 〜7 $ tev在PP碰撞中的奇怪强子产生。匹配奇怪的哈登族与喷气区域和基础事件区域有望帮助我们解开在硬和软工艺中产生的奇怪颗粒。通过在Pythia8框架中实现的颜色重新连接和颜色绳索机制，研究了奇怪的黑龙的产量和相对产生。发现可以通过颜色重新连接和颜色绳索组合效应来合理地描述包含性的奇怪强子生产。通过修改的弦乐片段化机制引起了奇怪的巴里昂产生的显着依赖性增强，这表明在硬过程和软过程中，奇怪的巴里昂增强型持续存在。发现，与射流形状分析技术相比，与弦片碎片图中的其他奇怪的黑龙相比，多晶型重子与射流轴更为准确。对这些相关的奇怪强子制作的未来实验检查将为小型系统中陌生增强的起源提供更多的见识。
Strange hadron production in pp collisions at $\sqrt{s}~=~7$ TeV is studied in jets and underlying events using the PYTHIA8 event generator. Matching strange hadrons to the jet area and the underlying event area is expected to help us disentangle the strange particles produced in hard and soft processes. The yield and the relative production of strange hadrons dependent on the event multiplicity are investigated with the color reconnection and color rope mechanisms implemented in the PYTHIA8 framework. It is found that the inclusive strange hadron productions can be reasonably described by the color reconnection and color rope combined effects. A significant multiplicity dependent enhancement of the strange baryon production in the jet area is observed induced by the modified string fragmentation mechanisms, indicating the strange baryon enhancement persists in both the hard and the soft process. Multi-strange baryons are found to be more collimated with the jet axis than other strange hadrons in the string fragmentation picture with the jet shape analysis technique. Future experimental examination of these jet related strange hadron productions will provide more insight to the origin of strangeness enhancement in small systems.
