Abstract
We report on the measurements of jet fragmentation in Pb+Pbcollisions with the ATLAS detector at LHC. The data were collected during 2011 heavy ion run providing Pb+Pbcollisions at SQUARE ROOTsNN=2.76TeV.
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.
