HEAVY-ION RESULTS FROM THE CMS EXPERIMENT

The Compact Muon Solenoid experiment at the LHC accelerator uses various physics observables to study a hot and dense medium created in heavy-ion collisions. Understanding of the medium properties requires conducting studies for different colliding systems; these include PbPb collisions but also reference pp and pPb data. In this paper, an overview of some selected experimental results concerning collective effects, the jet-quenching phenomenon as well as the suppression of quarkonium states is presented. A special emphasis is put on the results obtained for recently acquired pPb data.
