  A broad range of new experimental data and theoretical results on the
properties of hadronic matter under extreme conditions have been reported at
Quark Matter 2012 conference. At this conference the scientific community was
presented with a variety of measurements from the 2011 lead-lead LHC run using
hard probe observables. Many measurements, such as boson-jet correlations,
production rates of the b-jets, high precision jet fragmentation and others
were shown for the first time. The new data from the LHC was matched by new
techniques and analyses coming from RHIC experiments. This proceeding
summarises the new measurements with high-p_T particles and jets and attempts
to provide a theoretical explanation for the novel results presented at the
conference
