Diffraction, forward physics and soft QCD results from CMS

Understand

We report on the recent CMS measurements of soft hadron-hadron production, including the measurements of inclusive single- and double-diffractive cross sections, as well as the measurement of pseudorapidity distributions, and of the leading charged particle and leading jet cross sections.

• We present the cross sections for low-pT forward jets production, and production of dijets with large rapidity separation (central-forward, and forward-backward jets).
• Studies of double parton scattering using four-jet and W+2-jet events, and the cross sections for Drell-Yan with associated jet production are discussed as well.
• The results, corresponding to the proton-proton center-of-mass energy of 7 or 8 TeV, are compared to predictions of various Monte Carlo models.
