| Abstract: | 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 length L, 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 Brownian k
⊥-broadening effect, respectively. However for large path length the minimum and maximum disappear. |
