Soft and hard QCD highlights from CMS

Studies of inclusive and identified hadron production in proton-proton collisions, including charged particle transverse momentum, pseudorapidity and event-by-event multiplicity distributions at $\sqrt{s} = 0.9$, 2.36 and 7~TeV are shown. A measurement of the underlying activity in scattering processes with a transverse momentum scale in the several GeV/$c$ region is presented. Results on two-particle angular correlations and Bose-Einstein correlations are presented. We also show measurements of the forward energy flow in Minimum Bias events and in events with hard jets produced at central rapidities, as well as measurements of the inclusive forward jet cross section and of associated production of forward and central jets. Results are compared to various Monte Carlo models and to perturbative QCD calculations.
