In relativistic heavy ion collisions, hard probes have been used to study and characterize the deconfined medium created in these collisions. The strong suppression of high –pT hadrons observed in heavy ion collisions at RHIC indicates the interaction of high energy partons with a dense colored medium prior to hadronization. The anomalous J/psi suppression observed in nucleus collisions at SPS and RHIC suggests that a deconfined medium has been created in these collisions but how this suppression is caused is not yet clear. I will first review the main results from hard probe observables at RHIC and then I will concentrate on the new possibilities that the wider kinetic range at the LHC will offer and on how ALICE will use them to better characterize the medium produced in these collisions.
