论文摘要
重量味的Hadron是研究在RHIC和LHC超相关重型离子碰撞中产生的热和致密QCD培养基的特性的独特探针。横向球体是用于将码头和各向同性事件与事件样本库分开的事件 - 故事变量之一。这项研究旨在通过横向动量光谱，双重差异产率以及J/$ψ$的平均横向动量，$ \ rm d^{0} $和$λ_{C}^{+} $作为带电型型多重性和横向跨副群的功能来了解重型流动的生产动力学。进一步研究了魅力夸克的雅德可能性，横向球形依赖比（例如$λ_{c}^{+} $/$/$ \ rm d^{0} $和$λ^{0} $/$ k^{ - } $。对于当前的分析，将通过使用4C调谐的Pythia8对PP $ \ sqrt {S} $ = 13 TEV生成事件，这在解释LHC Energies处的重量品味颗粒的产生非常成功。
Heavy-flavored hadrons are unique probes to study the properties of hot and dense QCD 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/$ψ$, $\rm D^{0}$ and $Λ_{c}^{+}$ as a function of charged-particle multiplicity and transverse spherocity. Further to investigate the possibility of hardonization of the charm quarks, transverse spherocity dependence ratios like $Λ_{c}^{+}$/$\rm D^{0}$ and $Λ^{0}$/$K^{-}$ are studied. For the current analysis, the events are generated by using 4C tuned PYTHIA8 for pp at $\sqrt{s}$ = 13 TeV, which is quite successful in explaining the heavy-flavor particle production at the LHC energies.
