研究了有限喷注锥外轻夸克和重夸克的介质诱导胶子辐射角分布。我们发现,当路径长度L很小时,真空与介质诱导辐射之间的相消干涉效应对胶子辐射起重要作用,导致介质诱导能量损失为负值。对于小路径长度的重夸克,在一定角度外介质诱导的辐射能量损失在小角度处有一个最小值和一个最大值,这分别是由死锥效应和Browniank展宽效应引起的.然而,对于大的路径长度的最小值和最大值消失。
The medium-induced gluon radiation angular distributions of light quarks and heavy quarks outside a finite jet cone are studied. We find the effect of destructive interference between the vacuum and medium-induced radiation plays an important role in gluon radiation for very small value of path lengthL, which leads to the negative value of medium-induced energy loss. The medium-induced radiative energy loss outside an angle for heavy quarks is found to have a minimum and a maximum at small angle for small path length, which are caused by dead cone effect and Browniank⊥-broadening effect, respectively. However for large path length the minimum and maximum disappear.
