Soft QCD from ATLAS and CMS    [PDF]

Measurements of hadron production in pp collisions by the ATLAS and CMS
experiments are presented, including charged particle transverse momentum,
pseudorapidity and event-by-event multiplicity distributions at sqrt(s) = 0.9,
2.36 and 7 TeV, for NSD and inelastic events. Diffraction is studied with
either diffraction enriched or suppressed data samples. Total inelastic
cross-section as well as gap cross-section measurements are shown. Measured
spectra of identified strange hadrons, reconstructed based on their decay
topology, are also discussed. Comparisons to several QCD Monte Carlo models and
tunes are exhibited. Results on two-particle angular correlations over a broad
range of pseudorapidity and azimuthal angle in pp collisions are presented.
Underlying event activity are studied with different hard probes: tracks,
trackjets, calorimeter clusters, or in Drell-Yan events.
