Abstract

Recent CMS soft QCD results in proton-proton collisions at three LHC center-of-mass energies are highlighted. The properties of minimum bias events such as charged particle transverse momentum spectra, event-by-event multiplicity distributions, the production of the strange particles are measured. Particle correlations, such as long- and short-range angular correlation as well as Bose-Einstein correlation are studied. Characteristics of the underlying event and comparisons to MC tunes have been made.
