Underlying event, minimum bias and forward energy flow measurements with CMS

A measurement of the underlying activity in scattering processes using leading track-jet and Drell-Yan events with energy scale over wide range has been presented. 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.Results on two-particle angular correlations. We also present the measurements of the forward energy flow in Minimum Bias events and in events with hard jets produced at central rapidities, as well as in the events having W/Z boson in central region. Results are compared to various Monte Carlo models and to perturbative QCD calculations.
