CMS low pT QCD results

The CMS soft QCD results in proton-proton collisions at different LHC centre-of-mass energies are reviewed. The first part of the review focuses on the basic kinematic measurements of charged tracks and identified hadrons in minimal bias proton-proton interactions. The second part reports the short- and long-range correlation studies with emphasis on the results exploiting a special trigger specifically developed for large multiplicity events. The third part concentrates on the underlying event phenomenology in jet and Drell-Yan events. Some relevant highlights from the CMS heavy ion program are also discussed.
