  We review up-to-date results on high-pt particles and jets in heavy ion
collisions by three major LHC experiments, ALICE, ATLAS, and CMS. Results of
analyses of 2010 and 2011 Pb+Pb data at $\sqrt{s_{NN}} = 2.76$ TeV are
discussed. We concentrate mainly on results by fully reconstructed jets and
discuss similarities and important differences in measurements among
experiments. We point to the importance of understanding the results in a view
of difference between quark-initiated and gluon-initiated jets
