论文摘要
在这项工作中,我们提出了一种显示强子及其夸克成分核修饰因子之间对应关系的方法。基于毕5thia6.4的Parton和Handron级联模型Paciae用于计算0-5 \%中心$ PB+PB $ collisions $ \ sqrt {s_ {nn}} $ = 2.76 tev中的0-5 \%中心$ PB+PB $ collisions中的强子及其夸克成分核修饰因子。事实证明,强子核修饰因子通常小于其夸克成分。另一方面,在我们的研究中表明,“死锥效应”更有可能与夸克和介子一起识别,但显然没有在巴里昂州。
In this work, we propose a method to show the correspondence between hadron and its quark component nuclear modification factors. A parton and hadron cascade model PACIAE based on the PYTHIA6.4 is employed to calculate the hadron and its quark component nuclear modification factors in the 0-5\% most central $Pb+Pb$ collisions at $\sqrt{s_{NN}}$=2.76 TeV. It turns out that the hadron nuclear modification factor is usually smaller than that of its quark component. On the other hand, it is shown in our study that the "dead cone effect" is more likely to be identified with the quarks and mesons but not with the baryon states obviously.
