Soft QCD Results from ATLAS and CMS

The ATLAS and CMS Collaborations at the LHC have measured a wide range of properties of soft particle production. These include charged particle differential distributions, forward-backward and azimthual correlations, azimuthal ordering of hadrons, event shapes and identified particle production. Many of the measurements can be used to develop and tune Monte Carlo models. The inclusive and diffractive cross sections have been measured using vertex counting, particle tags, and rapidity gaps. In addition, the mean transverse energy flow and its density is measured out to forward rapidities providing a sensitive probe of models of the underlying event and QCD radiation.
