论文摘要

在这项工作中,相对基础事件(UE)横向多样性活动分类器($ r _ {\ rm {t}} $)用于研究质子 - 普罗顿碰撞中的奇怪和多晶体生产。我们对$ r _ {\ rm {t}} $的研究将允许解开这些粒子,这些粒子源自软QCD过程。我们已经使用了Pythia 8 Monte-Carlo(MC),并使用了不同的颜色重新连接和绳索强化模型的实现,以$ \ sqrt {s} $ = 13 TEV以质子 - 普罗顿碰撞数据来证明质子 - 普罗顿碰撞数据。在低和高的横向活性区域中,广泛讨论了奇怪的和多震颤哈子的相对产生。在此贡献中,随着$ r _ {\ rm {t}} $的增加,相对奇怪的强子产生得到增强。与介子相比,这种增强对于奇怪的重子很重要。此外,粒子比作为$ r _ {\ rm {t}} $的函数确认了新颜色重新连接(newCr)中的baryon增强功能,而绳索模型仅证实只有奇怪的夸克含量的baryon增强。对此类结果的实验​​确认将为横向区域中的软物理学提供更多的了解,这对于基于强发和颜色重新连接方案进行各种曲调非常有用。

In this work, the relative Underlying Event (UE) transverse multiplicity activity classifier ($R_{\rm {T}}$) is used to study the strange and multi-strange hadron production in proton-proton collisions. Our study with $R_{\rm {T}}$ would allow to disentangle these particles, which are originating from the soft and hard QCD processes. We have used the PYTHIA 8 Monte-Carlo (MC) with a different implementation of color reconnection and rope hadronization models to demonstrate the proton-proton collisions data at $\sqrt{s}$ = 13 TeV. The relative production of strange and multi-strange hadrons are discussed extensively in low and high transverse activity regions. In this contribution, the relative strange hadron production is enhanced with increasing $R_{\rm {T}}$. This enhancement is significant for the strange baryons as compared to mesons. In addition, the particle ratios as a function of $R_{\rm {T}}$ confirm the baryon enhancement in new Color Reconnection (newCR), whereas the Rope model confirms the baryon enhancement only with strange quark content. Experimental confirmation of such results will provide more insight into the soft physics in the transverse region, which will be useful to investigate various tunes based on hadronization and color reconnection schemes.
