  Studies of hadron production in proton-proton collisions, including charged
particle transverse momentum, pseudo-rapidity and event-by-event multiplicity
distributions at \sqrt{s} = 0.9, 2.36 and 7 TeV are shown. Measured spectra of
identified strange hadrons, reconstructed based on their decay topology, are
also presented. Comparisons to several QCD Monte Carlo models and tunes are
discussed. Results on two-particle angular correlations over a broad range of
pseudo-rapidity and azimuthal angle in p-p collisions are presented at both
\sqrt{s} = 0.9 and 7 TeV. In high multiplicity events, a pronounced structure
emerges in the two-dimensional correlation function for particle pairs with
intermediate transverse momentum of 1-3 GeV/c. Furthermore, Bose-Einstein
correlations between identical particles are measured in samples of
proton-proton collisions at \sqrt{s} =0.9 and 7 TeV. Finally, a measurement of
the underlying activity in scattering processes with a p_T scale in the several
GeV region is also presented.
