Observation of Medium-Induced Modifications of Jet Fragmentation in Pb-Pb Collisions at √{sNN }=5.02 TeV Using Isolated Photon-Tagged Jets
Measurements of fragmentation functions for jets associated with an isolated photon are presented for the first time in p p and Pb-Pb collisions. The analysis uses data collected with the CMS detector at the CERN LHC at a nucleon-nucleon center-of-mass energy of 5.02 TeV. Fragmentation functions are obtained for jets with pTjet>30 GeV /c in events
