Heavy ions: jets and correlations

Strongly interacting matter can be studied in the laboratory under extremely high energy density and temperature by creating ultrarelativistic heavy-ion collisions. Jets and correlations are invaluable tools to explore properties of this form of matter. Jets are sensitive to the interactions between energetic partons and the medium and to nuclear parton distribution functions, while correlations reveal details about the collective motion of the constituents of this fluid-like phase and can shed light on the role of the initial state properties. A few recent developments and results from the LHC and RHIC accelerators are discussed in this talk.
