Studies of the internal structure of jets, and of events with high jet
multiplicities, provide a stringent test of QCD. These important standard model process may also hide, or reveal, new physics. We present measurements of multijet cross sections and distributions, of the subjet
structure in high-pT jets, and of the distribution of charged particle
inside jets.

We present measurements of the forward (3 < |eta| < 5) energy flow in minimum bias events and in events with either hard jets or W and Z bosons produced at central rapidities, as well as measurements of the inclusive forward jet cross section and of associated production of forward and central jets. Results are compared to MC models with different parameter tunes for the description of the...

A measurement of the inelastic cross section for proton-proton collisions at 7 TeV centre-of-mass energy is present. In addition the separate contributions of single- and double-diffractive dissociation are measured, and the differential cross section as a function of rapidity gap is presented.

A measurement of exclusive production of muons pairs in pp collisions at \sqrt{s} = 7 TeV is presented. Events are selected requiring the observation of two muons and no other activity in the CMS detector. Single differential cross sections are obtained as function of the dimuon transverse momentum, invariant mass and acoplanarity for dimuon pairs with an invariant mass above 11 GeV. Data are...

We report on studies of exclusive dimuon production, using LHCb experimental data. Muon pairs can be exclusively produced by two-photon fusion (a QED process ideally suited to obtaining a precise integrated luminosity measure), or by resonance production. We show results for exclusive dimuon production, and first observations of the exclusive J/Psi, Psi(2S) and Chi_c states, obtained with 37...
