摘要:

用Pythia 8事例发生器研究了由ALICE实验测量的$\sqrt{s} = 7$和13 TeV的p-$-$-p碰撞中粲介子产生的多重数依赖性.在不同横动量($p\textsubscript{T}$)范围内,由ALICE实验测量的D介子和$J/ψ$的相对产额($\rm Yield/\langle Yield \rangle$)与相对带电粒子多重性的关系与Pythia 8模型在微观过程框架内的估计值基本一致.还计算了不同$p\textsubscript{T}$间隔($1 < p_{T} < 20$ GeV/ $c$)下,在$\sqrt{s} = 7$ TeV和$\sqrt{s} = 13$ TeV的p-$-$-p碰撞中B介子的相对产额.

英文摘要:

The multiplicity dependence of the production of the charm mesons in p$-$p collisions at $\sqrt{s} = 7$ TeV and 13 TeV as measured by ALICE experiment has been investigated using Pythia 8 event generator by studying the effect of various processes at partonic level such as the effect of different modes of color reconnections and rope hadronization. The relative yields ($\rm Yield/\langle Yield \rangle$) of D-mesons and $J/ψ$ as a function of relative charged particle multiplicity for various transverse momentum ($p\textsubscript{T}$) ranges as measured by the ALICE experiment are in reasonable agreement with the estimations of Pythia 8 model within the framework of microscopic processes. The relative yields of B mesons for various $p\textsubscript{T}$ intervals ($1 < p_{T} < 20$ GeV/$c$) have also been predicted in p$-$p collisions at $\sqrt{s} = 7$ TeV and $\sqrt{s} = 13$ TeV.
