Jet fragmentation with the ATLAS detector

We report on the measurements of jet fragmentation in Pb+PbPb+Pb collisions with the ATLAS detector at LHC. The data were collected during 2011 heavy ion run providing Pb+PbPb+Pb collisions at sNN=2.76 TeV. These measurements are expected to provide an insight into the modifications of jets initiated by partons passing through hot and dense QCD matter created in heavy ion collisions.
