Description
Jet shape gives the internal energy distribution of a jet and its
alteration in heavy-ion collisions relative to hadron-hadron reactions
has recently attracted a lot of attentions. In this talk
we investigate the medium modification of differential jet
shapes in heavy-ion collisions within the framework of QCD resummation
at NLO for pp baseline and PYQUEN parton energy loss model in AA
reactions. A centrality-dependent nuclear modification of differential
jet shapes and their comparison of experimental data are present.
Summary
It is shown that the differential jet shapes are significantly
modified after fast parton propagated the hot and dense nuclear matter
created in this reaction. The angular distribution of medium induced gluon
ratiation is close relative to the medium correction of jet shapes. In
peripheral collisions, the jet shapes in heavy-ion collisions are
similar to those in pp collisions.
