Description
A high-$p_{T}$ jet suppression first observed at RHIC has been reported also at the LHC.
The ALICE collaboration has recently reported an observation of an enhanced intra-jet yield of charged particles associated with the high-\pt{} trigger particle ($I_{\rm AA}$) in central \pbpb\ collisions at \snn=2.76 \tev\ which may be also interpreted as a hint of the modification of the fragmentation function due to induced gluon radiation.
In order to study further the nature of the intra-jet correlation yield enhancement an analysis of the jet-fragmentation transverse momentum was performed. Modification of this distribution with the centrality of the collision will be presented. A possible path length dependency of the induced radiation is studied using a comparison of the two-particle correlation for different orientations of the trigger particle with respect to the event plane and comparing the jet-fragmentation transverse momentum distribution measured in different event-by-event anisotropy classes.
