Heavy-flavored hadrons are unique probes to study the properties of hot and dense quantum chromodynamics medium produced in ultra-relativistic heavy-ion collisions at RHIC and the LHC. Transverse spherocity is one of the event-topology variables used to separate jetty and isotropic events from the pool of event samples. This study aims to understand the production dynamics of heavy-flavors through the transverse momentum spectra, double differential yield and mean transverse momentum of J/ψ, D 0 and as a function of charged-particle multiplicity and transverse spherocity. Further to investigate the possibility of hadronization of the charm quarks, transverse spherocity dependence ratios like /D 0 and Λ0/K − are studied. For the current analysis, the events are generated by using 4C tuned PYTHIA8 for pp at = 13 TeV, which is quite successful in explaining the heavy-flavor particle production at the LHC energies.

使用 PYTHIA8 在 = 13 TeV 时研究具有事件拓扑结构和质子 + 质子碰撞多重性的重口味与轻口味难题
重味强子是独特的探针,用于研究在 RHIC 和 LHC 的超相对论重离子碰撞中产生的热致密量子色动力学介质的性质。横向球形度是用于从事件样本池中分离码头事件和各向同性事件的事件拓扑变量之一。本研究旨在通过横向动量谱、双微分产量和J / ψ、D 0 的平均横向动量以及作为带电粒子多重性和横向球形度的函数来了解重口味的生产动态。进一步研究粲夸克强子化的可能性,横向球度依赖比如/ D 0和 Λ 0 / K -被研究。对于当前的分析,事件是通过使用 4C 调谐 PYTHIA8 生成的,pp = 13 TeV,这非常成功地解释了 LHC 能量下的重味粒子产生。
